Of course, this is made easier by the fact that each deck contains a Sol Ring (#1 card in Commander) and a Commander's Sphere (#3 card in Commander), but Open Hostility gets both Skullclamp and Lightning Greaves, which rank in the top 20 cards in Commander
These serve to keep Valgavoth in play as long as possible, and I feel are essential to a strong build
Choosing enchantments that build momentum keeps your Commander deck consistent, especially against removal or the grind of late game
