Satoru, Mumen Rider

Whenever you cycle a card, you may pay life
equal to the cycled card's converted mana cost.
If you do, you may exile that card with a Justice
counter on it. You may play cards with Justice
counters on them from exile by paying their
cycling cost.
Satoru, Mumen Rider gets +1/+1 for each spell
you own in exile with a Justice counter on it.
