Whenever Dragonhawk enters or attacks, exile the top X cards of your library, where X is the number of creatures you control with power 4 or greater. You may play those cards until your next end step. At the beginning of your next end step, Dragonhawk deals 2 damage to each opponent for each of those cards that are still exiled.
The delayed triggered ability created by Dragonhawk's last ability counts only cards that were exiled by the ability that created it. It doesn't count cards exiled by previous instances of Dragonhawk's last ability or by the abilities of other Dragonhawks you may have controlled previously.

You pay all costs and follow all timing rules for cards played this way. For example, if the exiled card is a land card, you may play it only during your main phase while the stack is empty.

The value of X is calculated only once, as Dragonhawk's last ability resolves.
