FLIP: Take control of 1 monster on your opponent's side of the field until the end of the turn that this card's effect is activated. When the controlled monster attacks, it can attack your opponent's Life Points directly.
Take control of the enemy's monster and then use dimensional gate to banish it. When the effect of the gate in the gy is activated, the monster stay in your field. A very easy way to change the control of monsters (and clean the spells/trapd, if you use storm to destroy dimensional gate).
So my opponent had three monsters on their side of the field, one of them a face-down Jowls of dark demise. I attack the jowls and its effect activated as it should. When he targeted my monster, it got destroyed because his field was full. I don't think the card should work that way.
The card works as intended, because when it flipped, the effect of taking control enemy monster activated, and because the field is full, instead taken its destroyed. The same case happened to parasite paracide with full field on the opponent side, its destroyed and the effect not activated and straightly sent to the owner graveyard. Sorry for bad english
This card is amazing, and highly under-rated.
Try thinking outside the box in it's usage, and take a hint from the image of the deck posted by "Italoipo".
Pair this car face down with traps to protect it for 1 turn. "A feint plan" - prevents any attack of face downs for 1 turn. Enemy controller, or "windstorm of etaqua".
Know that once it flips, it's exposed in atk position with 200hp, and work with it.
If you flip, and take enemy card, they can be face up or down, doesn't matter.
The taken card can be used in tribute summons immediately! So grab their card, then tribute it, and your atk facing Jowls . . now you've got a lev 7 or higher alone on the field.
I used Jowls to grab a "skilled red magician" that had 4 tokens on it, activated his skill to go thru my own deck and summoned an archfiend...nasty.
How many cards did your opponent have on the field before it was destroyed? If it flips and they control 3 monsters then when your monster transfers to their side it is automatically sent to the graveyard.
I MADE THIS CARD FAMOUS!
Opponent summons Blue Eyes Ultimate Dragon!
