This 2/2 Goblin was introduced in the Kamigawa block, a legendary five-drop with haste that can tap to make a token copy of another creature
Surprise Maneuver is an ability that allows the player to choose a character to banish whenever Prince Eric, Expert Helmsman is banished itself
It doubles your treasure mana production, it has haste and flying so it can be effective immediately, and it still benefits you slightly when your opponents remove it with spells
When it comes to large graveyard hate abilities I tend to think of them in two ways: exiling the whole graveyard in one shot - like Stone of Erech's backside - or exiling anything when it hits the graveyard from anywhere, like with Leyline of the Void and Rest in Peace
If instead the ability text read: Choose 1 Forward opponent controls, deal it 6000 damage, then it would not be possible for your opponent to target Rikku with this ability
Even then, would it be safe at all
