Alpine Houndmaster
Creature — Human Warrior
When this creature enters, you may search your library for a card named Alpine Watchdog and/or a card named Igneous Cur, reveal them, put them into your hand, then shuffle.
Whenever this creature attacks, it gets +X/+0 until end of turn, where X is the number of other attacking creatures.

The value of X is determined only as Alpine Houndmaster's last ability resolves. Once that happens, the value of X won't change later in the turn even if the number of attacking creatures changes.
