Yes but it usually makes no sense to have them in your deck. Remarkable exception is Snow graves that helps against recursion with any fraction mix, beings of ib can also be fine, but im not that sure and havent played with them as Im not buying any dreamlands untill they're reprinted 60 or there are no other new cards (hope for the first as there are some nice cards there).
Also note characters that can enter play without resource match via card effect like:
The Terror of the tides
Master of the Bannhammer… i mean Myths (needs restriction?, rise cost to activate 2,3?, some kind of effect steadfast? this card is too stupid)
Intruder from beyond
(hmm i wonder how strong no fraction neutral + best of those would be)
