At the beginning of your upkeep, draft a card from Arms Scavenger's spellbook, then exile it. Until end of turn, you may play that card.

Whenever one or more nontoken creatures you control die, investigate. This ability triggers only once each turn. (Create a Clue token. It's an artifact with ", Sacrifice this artifact: Draw a card.")

Reach

When Kraul Whipcracker enters the battlefield, destroy target token an opponent controls.

Lifelink

When Tolsimir, Midnight's Light enters the battlefield, create Voja Fenstalker, a legendary 5/5 green and white Wolf creature token with trample.

Whenever a Wolf you control attacks, if Tolsimir attacked this combat, target creature an opponent controls blocks that Wolf this combat if able.
