Hragam, Hurloon Warlord

Rampage X, where X is the number of
Barbarians you control (Whenever this creature
becomes blocked, it gets +X/+X until end of turn
for each creature blocking it beyond the first.)
When Hragam becomes blocked, there's an
additional combat phase after this one.
{r}{w}: Target non-Barbarian creature must
block Hragam this turn if able.
