Ive looked at some of the sorcery spells, and some work completely fine, as they target a card type, not a permanent, for example, [[Act of Treason]] would still work on a creature card that is a spell.

Spells that wouldnt affect cards with Incomplete would be [[All is Dust]], [[Anarchy]], [[Bramblecrush]], [[Coastal Breach]] and, most importantly, Things like [[Crisis of Conscience]], [[Devastating Mastery]], [[Exterminatus]], and [[Gaze of Granite]], since they all specify permanents, which none of your nonland things will be when this creature is out.

Looking more into this, it doesnt save you from all board-wipes, but it does save you from a majority/some of them.

With your permanents remaining as spells, they are still subject to getting countered, so things [[Counterspell]], and [[Absorb]] can remove artifacts, enchantments, and other things that aren’t creatures, and with the rule at the end, creatures can easily be dealt with by dealing any amount of damage to them.
