Yes, nothing stops you from doing it unless the effect removed the monster from the field.
Yes, there is nothing inherently within the tributing or summoning rules which would stop you from tributing a monster you summoned the same turn you summoned it. Obviously, due to the regular summon rules, you can not Tribute Summon the monster you just Normal Summoned on the same turn; it would count as two Normal Summons. But if the first summon was a Special Summon, you had used "Double Summon", or wanted to tribute it for an effect like "Enemy Controller", then it's totally fine to tribute that monster for them.
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.
Yes. Hardened Armed Dragon doesn't need to be face-up. The effect is not on that activates, it's just something that's checked after the tribute is paid.
You can only ever Tribute something that you control, unless specifically instructed to do otherwise. Cards like Lava Golem and Soul Exchange for example, are cards that specifically say the opponent's monster can be tributed.
No. If two things each cost $1, then you can't buy both with just one single $1 bill. It's the same situation in Yu-Gi-Oh, one tribute won't pay for two costs. A tribute summons need a monster to be tributed as a cost, and Mei-kou needs to tribute himself as the cost for his own effect. You can't let his tribute pay both costs, it's either one or the other.
Of course not. You cannot declare an attack on the opponent's lifepoints if they have a monster, unless one of your monsters has an effect that allows it to attack directly.You'll just have to deal with their monster using Spells or Traps, a monster effect, or by boosting the ATK of one of your monsters.
No, there's absolutely nothing of the sort. The monster goes to the graveyard, just like any other tributed monster.
If you flip summon a Man-Eater Bug with no other monsters on either side of the field, it WILL end up killing itself, as it must select a target & it's the only one to select. That said, if you just want to tribute it, there's no reason you have to flip summon it anyway. Monsters do NOT have to be face-up to be tributed, unless an effect otherwise says so. Just say that you're tributing it, send it the the graveyard & summon the monster you wanted to summon as normal.
Yes... you can Special Summon Exodia the Forbidden One by discarding him and using Monster Reborn, but you will not automatically win the duel. Exodia's effect will only work when it and the other four pieces of Exodia are in your hand.
Well, you look at what the monster's lv is (count the stars), then if it's a lv 5 or 6, then you need to send 1 monster from your side of the field to the graveyard to tribute summon it. If it's 7 or more, then it's 2 monsters. Some of them can't be tribute summoned at all, and need certain conditions to be summoned. Just remember that a tribute summon is a normal summon.
What's in italics is answering your question. The rest is just other helpful information. Answer from yugioh-card.com: If Ultimate Offering is face-up, you can activate its effect multiple times in the same chain.When you activate Ultimate Offering's effect, you pay the 500 Life Points as a cost at activation, and then the Summon occurs at resolution of Ultimate Offering's effect in that chain. This means that it is possible to Summon a monster in the middle of a chain with Ultimate Offering's effect.If you are using Ultimate Offering's effect to perform a Tribute Summon, you Tribute the monster when Ultimate Offering's effect RESOLVES and you perform the Tribute Summon, NOT when you activate Ultimate Offering's effect and pay the 500 Life Points.If your opponent activates a Trap Card, you can chain the effect of your face-up Ultimate Offering to the Trap Card to Tribute Summon Jinzo (if you had a monster on the field to Tribute) and negate the Trap Card's effect.You cannot flip Ultimate Offering face-up AND use its effect in the same chain; you must have Ultimate Offering face-up on the field before the current chain began.If you activate Ultimate Offering's effect to Summon, and your opponent chains Mystical Space Typhoon to destroy Ultimate Offering, the Summon does not resolve because Ultimate Offering is a Continuous Trap Card and is no longer on the field.You can activate the effect of a face-up "Ultimate Offering" during your Main Phase even if you have not done a Normal Summon yet this turn.
yes it just says 1 monster and doesn't have the "except this monster" text in the card.
