Tribute Doll

You cannot use "Tribute Doll" to Special Summon a "Special Summon-only" monster like "Dark Necrofear".

You can use Monster Tokens as a cost for "Tribute Doll".

If you Special Summon a monster with "Tribute Doll", you cannot activate "Diffusion Wave-Motion" on that monster because it cannot attack that turn due to "Tribute Doll"'s effect. However, you can use "Diffusion Wave-Motion" on the monster during your next turn.

You can combine "Soul Exchange" with "Tribute Doll" to Tribute your opponent's monster as the cost of "Tribute Doll".
