A few random ideas o.0

[Baily18]

Unsettled(Permanant)
Cost: 6 any(upgraded is 5)
When a creature is damaged, all creatures you control gain +2/+1 for 1 turn(doesnt stack). All Damage done to your creatures increases by 2 for 1 turn(doesnt stack).

Frozen Crusher(Frozen Obliterator)
Cost: 5 ( 7  )
Attack: 5/3( 7/5)
Ability:  deal 3 damage to  1 frozen creature. This is frozen for 1 turn.(Deal 4 damage.)

Power Plant(Power Generator) Permanant
Cost: 6  (6  )
Ability: Destroy 1 Aether Pillar/tower. Summon 1 Spark(65%) or 1 Photon(35%) (upped is only Ball Lightning)

Power plant is underpowered IMO

6 + sacrificing 1 pillar/tower to summon a creature that cost nothing to bring out.

As stated above the Power PLant is under powered as the creature summoned is easy to kill or dies on the first turn. Maybe if it spammed them (as in 2 Sparks) it could be more useful. But as it is scarificing a pillar for a creature that is free doesn't make a lot of sense.

I like the Unsettled. Maybe the cost is too little for it as you can play it on your first turn with only 2 towers but to raise it by 1 could fix that. So the effect only lasts til the end of your turn? Why not make it +2|+0 rather than up. I am glad you said it doesn't stack and that would drive me nuts. (I'd never use thunderstorm again).

The Frozen Crusher is an idea that has been thrown around a bit. Being able to deal damage to frozen creatures is a good thing. I am unsure how this would work but hey Otyugh likes Frozen Dragons fro Lunch. A good card. In some ways I would look at it as to summon and to use but thats just me, kind of the inverse to Trident.

Good work and glad to have the ideas flowing.

I think the Power Plant idea would be good if you simply got rid of the 'destroy a pillar' part. Make it cost 2 to put Spark in to play (upgraded would be a Ball Lightening)

I say give it a cost of 2, even though it's normally a free creature, because it would spammed like crazy if it was free; you could have 6 out and be doing 30 damage a turn. But a marginal cost to do 3 or 5 damage every turn isn't bad, and it would stack well with graveyard.
