Destroy target creature. It can't be regenerated. Its controller reveals cards from the top of his or her library until he or she reveals a creature card. The player puts that card onto the battlefield, then shuffles all other cards revealed this way into his or her library.

thegr8jr Its there incase someone is smart enough to target Fblthp and send him into our deck. With Polymorph we can destroy a thopter or servo we might have to then search our entire library get fblthp back on the field and draw two cards with Fblthp's ability.

@ DrkNinja That may be a bit too many, but it all kind of depends on the decks game plan focus. If you have a lot of other ways to profit from replaying artifacts like generating a bunch of tokens and drawing a bunch of cards then the deck is doing what it wants to do by repeatedly casting these artifacts for value generation and resource accumulation. I've found that these lines are certainly less effective than they would be in a deck helmed by the likes of Jhoira, Weatherlight Captain for example, but in mono blue you rather have to work with what's available. I've had some moderate success with the storm oriented lines in playtesting that was pretty nice, but definitely also not spectacular. I tried some Tidespout Tyrant stuff with Polymorph that felt pretty awful and switched over to attempting similar things with Proteus Staff which feels slightly better but I haven't had many games with that set up so its tough to say much about it.

No matter what if you're employing a Grindstone + Painter's Servant combo line then being able to hit all three opponents in one turn is nice, which is important to consider.

I usually use Polymorph on my Coiling Oracle in hopes of getting usually a Simic Sky Swallower or something better if I'm lucky.

Lazotep Plating would be an nice addition to your deck, because it creates a token with Hexproof until end of turn, allowing you to Polymorph it the turn you make it without any worries it could get killed. It can also protect you from discard.

What do you think about Kasmina, Enigmatic Mentor // Polymorph ? Play it similar to the old Baral, Chief of Compliance decks?

Not my first thought on a dovin deck, so my first thought would be to give the idea of what I saw with him in oathbreaker, Blightsteel Colossus as the only artifact in the deck, and Shape Anew as the signature spell (or colossus as only creature and Polymorph as the signature). the rest of the deck would mostly be treating the deck like a Edric, Spymaster of Trest deck with many 1 cmc hard to block creatures ( Bident of Thassa could be pretty sweet)

now for this deck, any sort of 1 cmc cantrip can help increase consistency, Arrester's Zeal in most cases won't be a good card for your deck (the pump with added flying won't really be relevant most cases), Dramatic Reversal if you play it most people will assume an Isochron Scepter is in your deck somewhere, so a Rally of Wings might be more relevant.

Apathy-Dance Ok, so traditional Polymorph decks work like this: the deck contains exactly one or two creatures. These should be large unanswerably powerful fatty. Emrakul, the Aeons Torn is the traditional choice, but there are plenty of options, like Iona, Shield of Emeria , Progenitus , and Kozilek, the Great Distortion . These must be the only creatures in the deck, or else you risk polymorphing into something else.

Then, the deck will have a 4-8 copies of Polymorph , and/or other redundant effects like Proteus Staff , Indomitable Creativity or Reweave .

Then, there will have a number of noncreature spells that make creatures. This can take the form of permanents that become creatures like Faerie Conclave or Guardian Idol . Or, it will be instants and sorceries that create creature tokens, like Dragon Fodder or Lingering Souls .

Now...the idea is as follows: you create a creature, then destroy your own creature with Polymorph, and find a copy of the big fatty in your deck, and put it on to the battlefield. Yeah, you lose the creature to Polymorph, but it would always be better to have the big fatty than the tiny critter.

But, the biggest problem that Polymorph decks face, is that the opponent can kill the creature Polymorph is targeting, and this will prevent any of the effects of Polymorph from happening. So, Polymorph decks have to pack hexproofing , counterspells , discard , bounce and other things to fight against removal and lock . And they usually need cards that assist finding the combo.

It is at this point that Amass becomes very appealing to me, because there is an Amass card that can fill each of those functions, and this means you don't need to specifically have any token generation, just noncreature amass spells. And then, with so many instants and sorceries, Invade the City could make a solid backup win condition.

Amass in Modern just does not seem like it is powerful enough to be played straight. There is one way I could see Amass competitively in Modern: Polymorph .

The amass spells do double duty: they have their effect, and they make a token that can be polymorphed.

Lazotep Plating has a unique effect: it creates a token with Hexproof. This covers up a weakness Polymorph decks have had, because tokens have always been vulnerable to kill spells that this can fizzle the combo. Even though this Hexproof is only until end of turn, if you try to polymorph it the turn you amass it, the opponent wouldn't be able to kill the token in response to Polymorph .

Toll of the Invasion can pull a removal spell from their hand, and make a token. If they had only one removal spell in hand, it'll be gone by the time the token is made, safely protecting it.

It would take 6 or 7 mana to safely Amass the Army and polymorph on the same turn, but there is still the possibility it can be done on turn 4.
