Updated OP with new set structure.
I'll start with these slots:
Slot : CthonicShadow Skimmer
5
| 4
Creature
5 | 1
Enters play Cloaked. (This is permanent unless it is removed.
When Shadow Skimmer is destroyed, generate an Evasion Ward.
Evasion Ward:
All creatures are Cloaked for 1 turn. (Card self-destructs after turn ends, like Sundial.)
: Alpha Strike : All cloaked creatures gain Momentum for 1 turn and lose Cloak. (Allows the card to have a more offensive functionality. This effect doesn't have to be included if people feel it's too much for the card.)Slot: GaianGene Splicer
3
| 2
Creature
2 | 1
If Gene Splicer would be destroyed, remove a Genesis counter from it instead.
: Place a Genesis Counter on target card. It cannot be destroyed this turn.
^Overall, a protective card that can allow it's other counter-generating allies to grow while protecting itself.
Slot: GaianChaotic Mutation
7
| 5
Spell
All creatures get +2 | +2 until the end of your turn. All your creatures with Genesis Counters get a random positive status effect. (Wisdom, Momentum, Adrenaline, Quintessence, Purify, etc...)
Place a Genesis Counter on each creature you control.
^Could also be a +1 | +1 for 5 | 3.
