SoFre dodge is better than Quint buff in most occasions, but SoFre dodge does not provide for AoE dodging. In this sense, SoFre dodging and Quint can be seen as roughly equal.A 1|3 creature that is immortal should cost no more than 3 if we go by immateriality cost as 1.5 times attack. Compare:An unbuffable version of Swift that also dodges AoE with four times the attack and the same cost and hp.
I like the idea. It's very simple and opens new strategies. The cost should be lowered since this creature does not have the SoFre ability to ignore shields, does it?
So... 3|2 cost and 2 atk works here?
