My first thought on this card was act positive, the 1 mana minion spam strat decep got is viable and strong, stats look kinda good ( has decent stats and put a lot of pressure on the board ), its sticky and yada yada yada, so i made a deck with it, a wide deception one, tested armory heist, the 4 mana jester thespian something, pretty much every new card i ended up testing, and turns out that galatea sucks, A LOT, and only galatea sucked that hard, every card had a act purpose, even if the purpose is making memes, i'm not even talking about the role it has with the summon random 1 mana creature, the actual problem is, galatea DOESN'T buff minions you summon on your board! the card doenst f work!!! cards like aspect juggler, corrupting influence, rollicking lyricist and appeal to mercy, the best cards from the archetype, don't benefit from galatea's effect! the actual effect of galatea is, when you play a creature from another domain FROM YOUR HAND, give it +1/+1, so the only cards that can benefit from galatea's effect is stolen plans and unlikely pact, the worst cards from the set btw, why this card was printed this way ? why the f it sinergizes with 10% of the set???
My suggestion is, make galatea work with summons on board, its that simple, just make the card do what is supposed to do lol XD, there is no point in making a card with almost zero interaction with the rest of the set, neither making it only interact with itself.
The card atm is at completely garbage tier, don't buy this card, don't play it, its completely trash.
note, i tested decep on ptr till it closed, idk if it was a bug, although from the text it seems its not a bug and the card is supposed to only buff what you act play, supporting a inconsistent strategy that has merely 3-4 cards, most of them not viable.
