Feran, Wizard of Frozen Waves

Whenever a spell or ability you control counters
a spell an opponent controls flip a coin. If it
lands on heads add {2}{s} to your mana pool at the
begining of your next precombat main phase.
If it lands on tails tap all non-land permanents.
"When everything hangs on a single moment, be sure
you choose the right moment" -Jace Beleren
