Activate this card by declaring 1 Monster Type and 1 Attribute; Special Summon this card as a Normal Monster (Level 4/ATK 1800/DEF 1000) with that Type and Attribute. (This card is also still a Trap Card.)
Excellent substitute for any Fusion monster that requires a certain Type or Attribute as one of the Fusion materials.
Can also be used to quickly fill your field with additional monster.
This card is still a trap card, vulnerable to backrow card removal plays.
This card is considered as Trap card in Graveyard, therefore you cannot use Soul Resurrection, Birthright, or Powerful Rebirth to Special Summon it from the Graveyard.
These are the Fusion monsters that allows 1 of the Fusion material to be either any Type or Attribute. With this flexibility, you can designate Swamp Mirrorer into the required Type or Attribute according to the Fusion Monster requirement and Fusion summon the monster.
You can Special Summon Swamp Mirrorer, then proceed to use Ties of the Brethren to Special Summon 2 monsters from your Deck with same Type and Attribute as Swamp Mirrorer, but different name. This will quickly swarm your Field with monsters. Since Swamp Mirrorer is a Normal Monster, you can use Order to Charge to destroy it and destroy your opponent’s monster.
Chain Reaction(skill) Can be used each time you activate a Trap card. Decreases your opponent's Life Points by 200.
This works alright with Gem-Knights since it lets you pick which Gem-Knight fusion you want. Play it with Pyroxene Fusion and you get some interesting plays where you can force your opponent to waste resources during the Battle Phase (eg. summon and attack with a regular Gem-Knight, opponent activates ECon, summon this guy and attack, opponent activates WoD, activate Pyroxene and fuse Swamp and Gem-Knight to get one of the Fusions out).
I'm just waiting for the day they give us Imperial Custom or Statue with Anguish Pattern to break these things. :P Also waiting for the day they give Odion a Trap Monster to drop. How has he not gotten one. (He doesn't even have a LEVEL-UP one, just the Starter Apophis.) C'mon, Konami, give him Quantum Cat or... Wow, there aren't really any other options left we're likely to get from Odion...
