Fblthp Enraged

When Fblthp Enraged enters the battlefield,
reveal the top card of your library. If Fblthp
wasn't cast from your hand, reveal the top 3
cards of your library instead. For each land
revealed this way, put it in your hand and put
a +1/+1 counter on Fblthp Enraged.
Discard your hand, then return Fblthp Enraged
to your hand: Deal X damage to each creature
and each player, where X is the number of lands
discarded this way.
