Six mana might be too steep for the cut-throat world of Standard, but I can definitely see Storm of Saruman making it into less competitive (and more fun) Commander decks
Casting Cost: Card Type: Legendary Artifact - Equipment Card Text: As long as it's your turn, equipped creature has hexproof and can't be blocked
It's an excellent protection spell that makes great use of its flexibility to adapt on the fly to the state of the game
If a spell "deals damage to any target," you can choose any creature or player (or planeswalker, if a player has one) as a target for that spell
However, thanks to its face Commander Bello, Bard of the Brambles, you can transform some of your Artifacts and Enchantments into creatures on your turn to have them bring the pain to your opponents (and give you some sweet card draw)
This card is best friends with Basilisk Collar and other deathtouch-granting equipment
