super OP, combined with aflatoxin (use it on ur own creatures)
add in some emphatic bonds to survive
and maybe some sundials and/or phase shields
and when u got enough, punch away...
Not particularly.
Fire Stall (i.e. Fire Lance OTK, backed up by Shard of Gratitude, Fahrenheit, Explosions, Fire Bucklers, and Rage Potions) does the job much more cleanly and doesn't require a complicated combo of filling the field to work -- just stall, save up
quanta, and bolt for the win.
approximately balanced.
1 damage per creature > 1 damage per 10 but not by too much. Maybe a small increase to 4|3?
However the effect does not fit with Gravity in my eyes. What is your reason for Gravity?
Not really sure about the cost -- both 3|2 and 4|3 sound reasonable. However, Gravity could use a small boost at the moment
Graviton Punch is a "Fire Bolt meets Chimera" kind of card. Since Gravity can already amalgamate creatures via Chimera, I felt that it could also combine their creatures' masses and unleash it as a force.
