no only if they are over 4 stars
Not quite. A Synchro Summon is a Special Summon. A Tribute Summon is the same as a Normal Summon, except that when you Tribute Summon you need to tribute monsters. Also you can Special Summon as many times as you want to in a turn, whereas you can only Normal Summon OR Tribute Summon once per turn, except with a card effect.
No, because Tribute Summon is treated as a Normal Summon. Monsters that require tribute for a special summon (Toon monsters, Destiny Hero Plasma) are still Special Summons, not Tribute Summons.
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.
Under normal circumstances, you are only allowed one Normal Summon per turn. A Tribute Summon is a kind of Normal Summon, meaning that if you wanted to do both in one turn, you'll need an effect that specifically lets you, like Double Summon. Note that a special summon that requires tribute, is not a Tribute Summon. You can perform those in the same turn as a Normal Summon.
You only need 2, like any other tribute monster that's level is 7+
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.
You don't need to sacrifice (tribute) any monsters to summon a level 4 monster. Level five monsters require one sacrifice.
You only need tribute for a special summon if the summoning text specifically says you do, ie, Toon Monsters.
The only way you can do it is by using an external effect. Ancient Rules can special summon it, for example, Mausoleum of the Emperor can let you pay 2000LP to Normal Summon it without tribute. Phoenix Gearfried's 'second summon' to activate its Gemini effect, does not require tribute. But unless you've got a specific way around it, you still need to tribute two monsters to summon it initially from hand.
You need to tribute 2 monsters to summon a Lv7 or more monster, so you need 2 for a 'Blue-Eyes White Dragon'.
You need to tribute 2 monsters to summon a Lv7 or more monster, so you need 2 for a 'Blue-Eyes White Dragon'.
Yes. To Special Summon a Level 7 Toon Monster, you must Tribute any two monsters on your side of the field. For Levels 5-6, you must Tribute one. For Levels 7 and above, you must Tribute two. High Level Toon Monsters follow the same guidelines as Tribute Summons. Note that it is considered a Special Summon, not a Tribute Summon.
