Rooting Kavu

Most green beaters of its era simply traded and stayed in the bin. This one comes with a graveyard-management clause that reads more like blue librarian tech than green stompy: on death, you may exile it to shuffle every creature card from your graveyard back into your deck. The effect points two directions at once. Against decks built to grind you out through your own dead creatures (reanimation, recursion, attrition that wants your graveyard full), it works as a defensive reset, denying targets and refilling your library with bodies you already cast. In the other direction, a 4/3 for four that puts your fallen creatures back where you can draw them again is a soft engine for an attrition battle of your own. The "you may" matters: shuffling is optional, so you never wreck your own graveyard plan when the trigger fires at an inconvenient moment, and you pay the cost of exiling the Kavu itself only when the refill is worth it. It belongs to the school of design that gives a fair creature a reason to die rather than just a stat line, anticipating graveyard interaction as a real axis of the game well before that became a routine concern in card development.
