The only final note Ill leave is that I did consider a strong throughline of extra attack step cards, but theres a sequencing issue (they dont work if you cast them off of Tetsuo)
Whenever any opponent casts a spell, you'll amass 1 Orcs
Nikara is a 2/2 with menace for three mana that lets you draw a card and lose one life if a creature with at least one counter on it under your control leaves the battlefield, Yannik, meanwhile, provides a means of triggering this effect
Next let's look at another good generic Sapphire card that has potential to find its way into decks
Goblins Cradle is on a Goblin, no less, and it needs Max Speed to even get there
You play Clone, which copies the Ravenous Chupacabra
