There's no question that ETB abilities are some of the most powerful and undercosted things in the game, so having more ways to effectively answer cards like Dockside Extortionist and Thassa's Oracle feels like a net positive
Whenever it deals damage, you can throw away your hand and draw equal to the number of artifacts you control, which, as any self-respecting cheerios player would know, simply means "discard nothing, draw your whole deck"
An ability of the equipped creature or an emblem you own that triggers when a creature "leaves the battlefield" will trigger twice if that creature leaves the battlefield by dying
Maybe it was a big bad with a need for metal hand prosthetics
Every time this card does combat damage to other players, you can choose to exile any of your nonland permanents and return them back into play, also retriggering their ETB abilities
