Seems quite overpowered. You basically have a 60% chance each turn to get an additonal creature (or other beneficial effect/ shard) out for only 1

?
For example, mind gate costs 4 to play, 2 to activate, the only benefit is to get anotehr card (on hand, not even played) and you still need the correct quanta to play it...
+ It does damage?
(I realise it is a weapon and should be better than a normal permanent), but still?
