Kadril, Clan Pyromaster

Partner with Recha, Gruul Wyrmbinder
The first time each turn a creature with
toughness four or more enters play under your
control, reveal the top three cards of your library.
You may choose a land card among them and
put it into play tapped. Put the remaining cards
into your hand or graveyard as you choose. When
you do so, Kadril, Clan Pyromaster deals damage
equal to their total mana value to any player.
