Whenever Raubahn attacks, attach up to one target Equipment you control to target attacking creature.
Suit up Raubahn (or another attacker) with cheap, powerful Equipment and start swinging early; his attack trigger lets you move Equipment around for free each combat, dodging summoning sickness and equip costs. Snowball his power with combat-damage and +1/+1 buffs until Ward pays for itself and he kills in one or two hits. Mono-red aggression plus reusable free equipment attaches lets you pivot blows toward whichever attacker matters most.
Free Equipment attach every combat saves enormous mana versus paying equip costs
Ward—pay life scales with his power, making him hard to spot-remove once buffed
Cheap two-mana commander that can deploy and threaten lethal extremely fast
Flexible attach can move auras of protection or evasion onto whatever attacker is unblocked
Mono-red lacks card draw and struggles to recover from sweepers
Ward keys off power, so a board wipe or bounce resets your whole investment
Equipment-heavy hands are clunky with no creature to carry them
No protection from blockers without dedicated evasion equipment
Vulnerable to fog effects and go-wide gum-up since he relies on connecting
