Mirror Force X TRAP When an opponent's monster declares an attack: Destroy all your opponent's Attack Position monsters
If that card is useless, then theyre at a disadvantage
Budget accordingly
Vampire Domination X TRAP Counter When a Spell/Trap Card, or monster effect, is activated while you control a "Vampire" monster: Negate the activation, and if you do, destroy that card, then, if it was a Monster Card, gain LP equal to its original ATK
(Some abilities can also target unexerted cards.) But not using them has less of a direct benefit - you dont need to defend your life points, as in MTG or Yu-Gi-Oh!, so leaving cards upright is typically only worthwhile if theyre likely to be challenged by your opponent and you need them for a future turn
The Grass-type starters are regularly known to be a top pick for many, although that is an argument that is often brought up for debate by players and collectors alike
