So it's useful against:
Lance/Siphon Life decks
Charger decks
Graviton/Gemini/maybe Dark Matter
Poison?
...and only when you have 16+ health remaining, plus you can't heal next turn.
I'm not seeing the real usefulness. Especially since you can't heal, wouldn't it only be useful if you were one turn away from a win? Or am I missing something?
Look at it this way
This card ise useful to any permeannt control deck, since it gains you 1 free turn for low cost, while no worry of your phase shield being destoryed, but the worst case... stolen
Besides, i know my example had been leaning towards mono-aether, but this in a duo deck open up alot of possiblitiy. Besides the healing part is to balance it, you can heal next next turn anyway. Example timestamp
1: A plays stardust, deals 20 damage
2: A press space bar, end the turn, SoG heals and Ais dealing damage with creature / weapon like normally at the end of turn
3: B plays whatever (note even if he want to this turn, he cant heal A)
4: B ends the turn, nothing deals damage or heals A
5: A plays cards like a normal turn now, heals CANT happen during or at the end of turn etc...
Corrected...
