Beetlzan, Demon of Gluttony

Indestructible, infect
Whenever a player taps a land for mana, you may
pay 2 life and create two 1/1 green Insect creature tokens with infect. (They deal damage to creatures
in the form of -1/-1 counters and to players in the form
of poison counters. A player with ten or more poison counters loses the game.)
Other Insect creatures you control get +1/+0 and
have infect
Creatures with counters on them can't block.
"My swarm will devour all that you treasure so dearly."
