The Amber and Sapphire starter deck is a very complimentary deck with cards that add buffs to other cards or can be combined and played off each other, with the two included foil cards being The Queen - Commanding Presence and Gaston - Intellectual Powerhouse
Therefore, you should ensure the price youre paying to cast this card initially isnt too high
Megamorph makes your creature slightly larger upon unmorphing, but the name and the uninspired bonus text left megamorph as one of the most disliked Magic mechanics of all time, to the point where designers have stated they'll likely never use the mechanic again
Goblin Trailblazer is pretty good as well because they have to commit more than one token to block it
Shadow the Hedgehog also works well with creatures that have haste or flash, and additionally has spell-blocking abilities that should prove very painful for opponents
If you also have a Coat of Arms out, youll have a massive army of metal liches eager to snuff out the light of the living
