{@R} Foggy Swamp Visions [TLA 102]

As an additional cost to cast this spell, waterbend X. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.)

Exile X target creature cards from graveyards. For each creature card exiled this way, create a token that's a copy of it. At the beginning of your next end step, sacrifice those tokens.
