If you guys know more good cards for the current side deck choices, feel free to post it here ^-^


You play Blackwing/Dark World/Archfiend/Evilswarm/Zombies/Ghostricks?
Shadow-Imprisoning Mirror says hello :3
[Negate all DARK monster effects activated on the field or in the Graveyard.]


You play Hieratic/Constellar/Lightsworn/a deck with thunder monsters/Fairys ( I do not know how to call them xD)
Light-Imprisoning Mirror says hello :3
[Negate all LIGHT monster effects activated on the field or in the Graveyard.]


You play a deck that is focused on summoning monsters Monsters from the graveyard?
Royal Prison says hello :3
[Monsters cannot be Special Summoned from the Graveyard]


You are running a lot of Xyz monsters?
Flying "C" says hello :3
[When your opponent Normal or Special Summons a monster(s) except during the Damage Step: You can Special Summon this card from your hand to the opponent's side of the field in face-up Defense Position. The controller of this card cannot Xyz Summon]

Xyz Encore is a much better side for xyz focused decks as well as against Verz

I think they are both equal. If he can not destroy or stop Flying "C" it can freeze his Extra Deck.
