Creature — Elemental
3 / 2
Flying
When Wavesifter enters the battlefield, investigate twice. (To investigate, create a Clue token. It's an artifact with "
, Sacrifice this artifact: Draw a card.")
Evoke
(You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters the battlefield.)
The tokens are normal artifacts. For example, one can be sacrificed to activate the ability of Breya's Apprentice and one can be the target of Break Ties.
