You have to summon them first - they equip by using their Ignition Effects, which can only be done when they are on the field in the monster zone.
no. you use ultimate offering to NORMAL SUMMON one extra monster (basically you get to summon to level 4 or lower monsters). To summon the god cards you need to tribute 3 monsters.
No, Divine Wrath can only be used against effects that activate. Most of the time, when a monster has a way to special summon itself, this is an inherent special summon, just like a normal summon, it does not use the chain. Because it doesn't use the chain, you can't chain an effect negation card to it, though you can use summon negation cards like Solemn Judgment. If the special summon is an activated effect (like Dandylion's effect to special summon tokens, or Gorz's effect to summon himself) then these can be stopped using Divine Wrath. But Cyber Dragon's special summon cannot.
yes, but only monster cards. you can special summon it in face-up defense or attack position.
yes, only if it is a level 4 or lower monster. other cards like a legendary ocean that can reduce a monster's level by 1 can let you normal summon a level 5 water- type monster without a tribute.
No, it can't be special summoned except by Fusion Summon, even if you summon it and it is destroyed, it can't be resummoned from the graveyard. However cards like Blue-Eyes Ultimate Dragon can be summoned with Monster Reborn, if you properly summon it first, and then it goes to the graveayrd.
No, a Set is not a summon, summon negation cards cannot be used against it.
Yes, you can tribute monsters for card effects and Tribute Summon the same turn you summon a monster. However, you cannot Normal Summon a monster and Tribute Summon on the same turn because you can only Normal Summon once per turn. Cards such as Double Summon and Ultimate Offering will let you do that.
no. you use ultimate offering to NORMAL SUMMON one extra monster (basically you get to summon to level 4 or lower monsters). To summon the god cards you need to tribute 3 monsters.
Only if the card specifically says it can summon a Ritual Monster, like Ritual Foregone. Otherwise, you can't do it, cards like A Hero Emerges, or Monster Gate, cannot special summon a Ritual Monster.Also if you summon the Ritual Monster properly, by Ritual Summon, and it is then sent to the graveyard for whatever reason, then you may bring it back to the field using cards like Monster Reborn. However you cannot simply discard a Ritual Monster from hand and try using Monster Reborn straight away, they are a form of special summon only monster, simply by being Ritual Monsters.
Basically, when you special summon a monster with 1500 or less ATK with cards like marauding captain, call of the haunted, or monster reborn, you can activate this card when your opponent has a face-up monster to special summon all copies of that monster. Your opponent can special summon all copies of his monster too, but that's a rare chance IMO.
Yes, just as long as you remember you are allowed only one Normal Summon per turn, and a tribute summon is a Normal Summon.So you could Special Summon a monster and tribute it for example.Also, you are free to tribute it as a cost for cards like Enemy Controller.
Solemn Judgment can negate summons that don't use the chain, by waiting until the monster is placed on the field, then negating the summon before it counts as being successful. When a summon occurs on the resolution of an activated effect, the summon is automatically successful when the effect resolves - but Solemn Judgment can chain to that activation and prevent the summon by stopping the effect resolution. So, if you Normal Summon, Synchro Summon, or perform a special summon that does not use the chain, such as Chaos Sorcerer, you can negate the summon as per the first bit above. If you special summon on resolution of an activated effect, such as Monster Reborn or Call of the Haunted, Solemn Judgment can chain to these activations and negate them. No resolution means no summon. But, note that Solemn Judgment can only chain to the activation of Spell or Trap cards. If the special summon occurs on the resolution of an activated monster effect, Solemn Judgment can't stop it. It can't chain to it, and as above, the summon is successful when the effect resolves. So that is why Solemn Judgment can't do anything against the triggered effect of Gorz the Emissary of Darkness, but is able to stop special summons that aren't by resolution, such as Chaos Sorcerer.
No, Divine Wrath can only be used against effects that activate. Most of the time, when a monster has a way to special summon itself, this is an inherent special summon, just like a normal summon, it does not use the chain. Because it doesn't use the chain, you can't chain an effect negation card to it, though you can use summon negation cards like Solemn Judgment. If the special summon is an activated effect (like Dandylion's effect to special summon tokens, or Gorz's effect to summon himself) then these can be stopped using Divine Wrath. But Cyber Dragon's special summon cannot.
With cards like refusion and instant fusion
yes, but only monster cards. you can special summon it in face-up defense or attack position.
No, when you 'second summon' a Gemini Monster, it doesn't actually leave the field. So any counters on it will remain, as will any lingering effects (such as Chain of Memories) and Equip cards will remain attached.
yes, only if it is a level 4 or lower monster. other cards like a legendary ocean that can reduce a monster's level by 1 can let you normal summon a level 5 water- type monster without a tribute.
