The Grandfather

Defender
Whenever you would play a creature, you may choose to play it face down instead. While the cards are face down, you opponents and you cannot interact with them.
At your upkeep, put a wierd counter on all facedown cards you control.
{w}{b}{t}: Turn all face down cards face up, and remove all counters from them. For each counter you remove, place that many +1/+1 counters on creatures you control.
