Reveler Runt

Whenever Reveler Runt deals combat damage to
a player, destroy target artifact they control with
mana value less or equal to Reveler Runt's power.
Whenever Reveler Runt attacks or blocks, if you
control another attacking or blocking creature
with greater mana value, Reveler Runt gets +1/+1
until end of turn. If that creature is a Satyr, put a
+1/+1 counter on Reveler Runt instead.
