Tyler's Tower

When Tyler's Tower enters the battlefield each opponent sacrifices a permanent. Draw cards
equal to the number of permanents sacrificed
this way.
Discard two cards: Draw a card.
Exile four cards from your graveyard: Draw cards
equal to the number of cards in target opponents
hand. Activate this ability only if an opponent sacrificed a permanent this turn and only once
each turn.
Tyler's Tower can be your commander
