supreme darkness yugioh booster box Yu-Gi-Oh! Opening and this set adds even more Yu-Gi-Oh! OCG Duel Monsters:‎ Supreme

You can only use 1 monster effect of "Performapal Laugh Maker" per turn, and only once that turn

The only change is that it's now always treated as a "Venom" card, so it can be searched and the 'This card is unaffected by "Venom Swamp".' text was no longer necessary

Once per turn, if you gain LP, even during the Damage Step: You can make all Plant monsters you currently control gain ATK equal to the LP gained, until the end of this turn

It is also a little easier to disrupt some of the life gain and the second body on Finks but for the price you pay these are minor things

These "symmetrical" artifacts impact the board equally, but Urza's ability to tap artifacts at instant speed gives you a way to break that symmetry to make sure that you will be the only player at the table actually casting spells
