During your turn, as long as Cloud is equipped, it has double strike and indestructible. (This creature deals both first-strike and regular combat damage. Damage and effects that say "destroy" don't destroy this creature.)
Equip abilities you activate that target Cloud cost less to activate.
Cloud is a dedicated Boros equipment Voltron commander: suit him up with cheap equipment, swing for double-strike commander damage, and close games fast. On your turn he's effectively unkillable while equipped (double strike + indestructible), so you protect the rest of your gameplan around keeping equipment attached and getting through. Each turn you deploy gear, reduce equip costs by , and reattach as needed to push lethal.
Built-in double strike makes commander damage (21) trivially reachable—often two connections.
Turn-cycle indestructibility shrugs off board wipes and most removal during combat.
The -off equip discount lets you move multiple equipments per turn for cheap, enabling explosive reconfiguring.
Cheap to recast and immediately threatening, keeping pressure consistent across the game.
