Just some Concepts/mechanics I've been thinking about, finally found a place to put them! (costs are only guesses, everything's probably OP/UP)
Spell - 6

- "Tremor" Your opponent's creatures are now Burrowed. Airborne Creatures are unaffected. Their unburrow cost is their casting cost.
Spell - 8

- "Stopwatch" Your opponent's creatures are delayed 1 turn. All Remaining Time Quanta is consumed.
Creature - 6

- "Hydra" 3/3 Adrenaline (to simulate multiple heads attacking)
Perm - 10

- "Gravity Well" Damage you would take is redistributed among your creatures. If you control no creatures, Gravity Well is destroyed. Maintence of 5

per turn.
Creature - 7

- "Doom Bringer" 0/1 Immortal. 4

"Death Touch" Target creature has 10% chance of dying. Whenever Doom Bringer kills a creature, it gets +2/0.
I've got more thoughts, but feedback on these would be appreciated!
