Main problem I see? It nearly always requires a trio.
AW-->Used in monos/duos (Require
or
)
Crusaders-->Used in duos (Require
and another element)
Artificer-->Used in trios and above (Requires
,
, and whatever element permanent you're copying)
If you want to focus on the effect of a creature, its better to tone down stats so it can be cheap to summon for its ability.
Also, any permanent that it copies has to retain the EXACT same as if it were a permanent mechanically. This would mean that a copy'd SoFre artificer would just act like another sofre (25%), not 50%.
Also, if this can let players break the 6 perm rule for a heavy price, which perms would people want to copy and why? I personally would not be willing to pay 5
+ 1 turn + 1
to just copy a permanent.
