Dalamadur

Beyond Comprehension - Dalamadur enters the
game with 10 +0/+1 and 5 +1/+0 counters.
(When Dalamadur attack, remove a +1/+0 counter
and when it blocks, remove two +0/+1 counters.)
For each +1/+0 counter removed from Dalamadur,
deal 3 damage to target and for each +0/+1 counter removed, gain 1 life.
If Dalamadur has no counters your next upkeep,
you loose the game.
