Paradox Heart

Partner with Rhanva, Friend of Beasts
Whenever a beast enters the battlefield, put a
static counter on the Paradox Heart.
{t}: Add one mana of any colour
{2}{t}: Remove all static counters from the
Paradox Heart and reveal X cards from your
deck, where X is the number of counters
removed this way. You may put any number
of beasts revealed this way with CMC X or
less onto the battlefield.
