mtg cards with metalcraft Ghalma's Warden [Scars of Mirrodin] Galvanic Blast doubles in damage from 2 to 4 Best Metalcraft Cards in MTG

All of the cards near the top of this list do both things, and should be your first includes in an MTG Rat Commander deck

Graha Tia: The calculus of profitable combat becomes a lot more difficult for your opponent if you have this scion in play

While the front side is good enough to see play on its own, the fact that it only has four defense counters makes it relatively easy to flip (a single Sheoldred, the Apocalypse attack gets the job done), and the backside offers a very powerful creature that can defeat a battle or kill a planeswalker each turn while potentially generating card advantage as well

This card has two strikes against it: it costs triple blue to cast (just like cousin bombs Arcanis and Future Sight from this block) and blue is generally a weak color in Onslaught/Legions/Scourge

I like it because it actually has a fights matter theme, giving you cards when you fight or when your creatures are blocked
