The top-down rule is that cards worded this way are ongoing abilities that merely have triggers which activate down the road. No specific ruling is needed, follow the top-down rule.
So it does not restrict it? or it does?
Play is defined as follows:
Play
You play an enhancement by attempting to activate its special ability (or numbers in
battle)
You play a character or multicolor site by putting it in your territory or your side of
the battle.
You play any other card type by putting it face up on the playing surface from hand,
deck, or discard pile due to your special ability or game action, except when you
discard a card from hand.
It seems that the ability is active already and therefore play is considered when its placed?
