Quick-Play Spell Card
Discard 1 Monster Card: Target 1 Xyz monster your opponent controls with ATK equal to or less than the discarded monster; take control of the targeted monster until the End Phase. You can shuffle this card from the Graveyard into the Deck to target 1 Xyz Monster in your Graveyard; return that target to the Deck.

Situational, since most maindecked monsters has less ATK than the extra deck monster.

Kogakuri Flash Spell: Fire
Quick-Play Spell Card
Activate this card when a FIRE Monster is removed from the field; Inflict damage to your opponent equal to the number of FIRE Monsters in your Graveyard x 200.

Bane of Core
Trap Card
Activate this card when your opponent activates a Monster Card Effect from their Graveyard. Negate that effect and Banish that monster.

Better be a counter trap. It's a good side deck card.

Malevolent Wraith
DARK/Level 3/700/900
[Zombie/Tuner]When this monster is Summoned: target 1 Level 4 or lower Zombie-type mosnter in your Graveyard; Special Summon that target. It cannot be used as Synchro Material Monsters except for the Synchro Summon of a Zombie-Type monster.

Need to negate the summoned monster's effect, since 1 card synchro should have some kind of restriction. Also depends on what level 7 zombie synchro that we have.

Enchanted Emporium
Continuous Spell Card
When a Spell Card activates; a player can place two Spell Counters on a card instead of 1.

Depends on other cards here. IIRC there's only a little card that use spell counter here.
