Jiraiya, the Toad Sage

Summoning Jutsu: Gamabunta - At the beginning
of your end step, create a 2/2 Frog creature
token named Gamabunta. If you already control
a creature named Gamabunta, put a +1/+1
counter on it instead.
Honored Sage Mode - During your turn, spells
you cast from your hand with mana value X or
less have cascade, where X is the greatest power
among frogs or toads you control.
