If no +1/+1 counter is put on it (perhaps because it left the battlefield while its evolve ability was still on the stack), then its last ability doesn't trigger
Three or four instants or sorceries chained together can result in big swings in damage that can take out player after player
The card's only real drawback is that if you flip it in combat, you won't get the first trigger from Holy Frazzle-Cannon until the next turn, which makes it a lot worse than something like Invasion of Gobakhan
Then exiling an artifact can come in clutch (looking at you The One Ring), and of course that board wipe at the end could possibly change the face of the game
Holos like Snorlax from Jungle and Dragonite from Fossil are classic collectibles
