If we're forcing multiple creatures into combat, we may as well make the decision easier for them
Shorikais tokens make cards like Parhelion II, Skysovereign, Consul Flagship, and Reaver Titan even easier to crew
Like most Magic: The Gathering cards, the value of Tragic Lesson depends on a few consistent factors: its rarity, the printing and finish (regular or foil), its physical condition, and the set it was printed in (Hour of Devastation)
However, you strongest are going to be your three song discard cards: We Dont Talk About Bruno, The Bare Necessities, and Sudden Chill
Simply tap Arcum and swap those tokens out for a Portal to Phyrexia, The One Ring, or even a Myr Battlesphere, and make even more Artifact Creatures to sacrifice again later
