When Sazh Katzroy enters, you may search your library for a Bird or basic land card, reveal it, put it into your hand, then shuffle.
Whenever Sazh Katzroy attacks, put a +1/+1 counter on target creature, then double the number of +1/+1 counters on that creature.
To double the number of +1/+1 counters on a permanent, put a number of +1/+1 counters on it equal to the number it already has. Other effects that interact with putting counters on it will interact with this effect accordingly.
