Roku's Mastery deals X damage to target creature. If X is 4 or more, scry 2. (Look at the top two cards of your library, then put any number of them on the bottom and the rest on top in any order.)

1, Sacrifice this creature: Destroy target artifact or enchantment.

First strike (This creature deals combat damage before creatures without first strike.)

Vigilance (Attacking doesn't cause this creature to tap.)

1, T: Look at the top card of your library. If it's a Bison card, you may put it onto the battlefield. If it's a creature card, you may reveal it and put it into your hand. Otherwise, you may put it into your graveyard.

Target creature gets +2/+2 until end of turn. Create a Clue token. (It's an artifact with "2, Sacrifice this token: Draw a card.")

This land enters tapped. As it enters, choose a color other than white. T: Add W or one mana of the chosen color.

As an additional cost to cast this spell, waterbend 5. (While paying a waterbend cost, you can tap your artifacts and creatures to help. Each one pays for 1.) Return up to two target creatures to their owners' hands. Draw two cards.
