So I know no one's prob listening but here's a few Hiding patented suggestions:
4 cost- Indestructible in assault zone, gains +2/+0 whenever he attacks
9 cost- Characters you control attack and additional time this turn. If a Character you control would die for the first time this turn, it survives on 1 health instead.
7 cost--> 6 cost
Mega Unit 1-
Pay 2: Remove target character you control from the game. When Mega Unit 1 leaves play, return all characters removed by Mega Unit 1 to play in the zone Mega Unit 1 was in.
pay 1: deal 4 damage to target character on the battlefield. This ability can only be used if Mega Unit 1 is deployed and can only be used up to 6 times a turn.
Mega Unit 3
Unstoppable, Shield 1
Sacrifice an artificial character: Mega Unit 3 gains Flying until end of turn.
Vasir the Chained Prince
Cost 7--> 5
Dragon of Summer Flame
When Patient Zero enters the deployed area, all characters in play become Undead in addition to their other subtypes.
Whenever an Undead character your opponent controls dies, it is raised to your support zone.
Pay 8: Destroy target character on the battlefield
Nysrugh the Insatiable
Consume 2, Unstoppable
When you deploy Nysrugh the Insatiable, he kills each character adjacent to him and gains power and health equal to each killed character.
When Nysrugh the Insatiable dies, all characters he has killed are returned to play.
Silfurstar the Fallen Crusader
If Silfurstar is killed by another character, remove him from the game.
At the end of the turn return him to play in your support zone transformed as a 10/10 and he kills the character that killed him.
Vis, the Furious
Unique Character- Human
When you deploy Vis, the Furious you may overcharge any amount of times, Vis, the Furious gains a Multistrike for each card you overcharged.
Whenever Vis attacks, she fully heals.
Thats all I got so far.
