Destroy it
Let me know in the comments or over on the Draftsim Twitter
It will be much less effective in other token decks that dont revolve around life gain, but still worth including for the ability to create tokens
For just three mana, one of each of the Bant colors, Morska comes down quickly, potentially as early as your second turn, and at the top of each of your turns you investigate, giving you a Clue token which you can use to draw a card in exchange for two mana
For this exact reason, I prefer to play some combination of Relic Barrier and Icy Manipulator along with one Winter Orb and at least one Howling Mine
The card can occasionally do work in the Affinity mirror by creating endless chump blockers, but more often than not, youll be swinging at each other with unblockable Kappa Cannoneers
