The centerpiece to any Gemini deck was born from Chemicritters. Fitting considering how easily they will adopt just about any Gemini monsters that are functionally generic.
Each turn, 1 Level 5 or higher Gemini monster you Normal Summon can be Summoned without Tributing. During your Main Phase, you can Normal Summon 1 Gemini monster in addition to your Normal Summon/Set. (You can only gain this effect once per turn.) Once per turn: You can target 1 card your opponent controls; banish 1 Gemini monster you control, that is treated as an Effect Monster and has gained its effects, until your opponent’s End Phase, and if you do, destroy that card.
Catalyst Field is crucial to Chemicritters (or any Gemini deck) for a few reasons. First point – once per turn you can normal summon a level 5 or higher Gemini monster without tributing. Then once per turn you can make an additional normal summon.
Did ya catch that? In addition to meaning you can just play Dioxogre, just play Phoenix Gearfried, just play Red-Eyes Black Flare Dragon – and that’s in addition – so you can then use your other normal summon to get their effects live.
This is an amazing feature – just that alone would make it a good field spell and anyone playing against Gemini monsters: if you see this card – hit it immediately. Because it means something very bad could happen. Maybe one of those previously mentioned monsters is coming out, or Oxy Ox for an XYZ play, Carbo Crab for set-up. This card is a playmaker.
This card also has its own unique destruction effect: target an active Gemini monster and banish it (until the end of your opponent’s next end phase) and target/destroy a card the control. So you temporarily bench a monster and then you can explode some of their stuff.
But you monster comes back effect and all. If you’re looking to resource gather, use this with Carbo Crab to get his effects and then “hide” him until the end of their next turn. You get the effects and keep him reasonably safe.
And this card is 110% generic so you can splash it into any variation of Gemini monsters.
Solid, solid card. Great job, Konami! Ya did good on this one!
