Purphoros, God of the Forge The original incarnation of Theros s mono-red god, Purphoros, God of the Forge is both a 6/5 indestructible creature and an Impact Tremors for just 4 mana
Im about out of words for the week, but I also want to give a mention to Praetors Grasp (already expensive, could get even more so), Fallen Shinobi, Nashi, Moon Sages Scion and Silent-Blade Oni (ninjutsu goodness for the top of their library), Thief of Sanity (more flying and stealing) and Mnemonic Betrayal (the Yawgmoths Will for their yards) as more cards that could see a significant spike in coming days as Tasha begins her non-benevolent reign over all
Both these cards play around the lifegain theme, which is hugely popular in Commander already
In your deck, lessons work as a regular instant or sorcery card
It comes from the 1994 MTG Antiquities set
Fun Ranking: Very Fun Mu Yanling, Wind Rider I kinda hate this card
