Veil of Summer Veil of Summer raised a lot of eyebrows when it was first printed, and its seen plenty of play everywhere its been legal since
The deck has three solid board sweepers in Farewell , Fumigate , and Organic Extinction
Weaknesses The deck has a very weak interaction suite
It's a repeatable draw engine and token generator built directly into your commander and it only costs three mana to deploy
Additionally, your best payoffs are Blood Artist effects that damage your opponents as your creatures die, which excel at forcing through the last couple points of damage even if your opponents stabilize with blockers
Most of the deck cant really be sideboarded out (I cant think of a matchup where I want to cut Monastery Swiftspear, Delver of Secrets, Brainstorm, Ponder, Gitaxian Probe, Stormchaser Mage, or Lightning Bolt) and diluting the synergies of the deck is dangerous, as the cards in the deck have a low power level relative to the rest of the format
