Jim, Entish Enigma

Creatures you control have lifelink.
Whenever a creature you control deals combat
damage to a player, create a chakra token.
When you control 7 or more chakra tokens, search
your library and select 7 cards from it, then
choose 5 of those cards at random and remove all
other cards in your library from the game.
Shuffle the remaining 5 cards.
As long as you control 7 or more chakra tokens,
Jim is indestructible and creatures you control
have flying
