When your opponent declares an attack while you control a monster: Target 1 face-up monster your opponent controls, except the attacking monster; take control of that target until the end of the Battle Phase, and if you do, it is attacked instead, and you proceed to damage calculation.
Yeah, just like the tcg now. Everything has to be chainable to be worth using.
Really not a hard card to pull off. Lots of decks work with multiple summons per turn. Worst case scenario, this card reduces damage you might have taken, and takes out an opponents card. two monsters with identical attack points takes em both out, plus I've used this card multiple times to end a duel. This can also be used similar to econ, to prevent their strongest monster from attacking. Pretty versatile card.
This card is not so good: it's waaay too situational. The thing is, even if the opponent has 2 monsters face up, he has to either
a) attack with weaker monster first
b) have 2nd monster in defence mode
Otherwise the monster you take control of will still deal damage to yourself. So if he has a 3k monster attack and you take control of his 1.6k attack monster, yeah you destroy the 1.6k monster but take 1.4k damage. Not worth it.
Never mind, I must've set the Trap Jammer in the same turn as opponent activated Magical Arm Shield.
This card reminds me of something nelson muntz would do: "why are you hitting yourself??"
"why are you hitting yourself?".. lmao
The troll factor and the screw up your opponent factor in this card is quite good.
