Temur in Premodern typically pairs aggressive green creatures with red removal (Lightning Bolt, Chain Lightning, Fireblast) and blue counterspell backup, making their spot removal the primary threat to your Dreadnought. Hydroblast and Blue Elemental Blast serve double duty — they can counter or destroy red removal spells targeting your 12/12, and can blow out a Kird Ape or other red creature if needed. Daze gets significantly weaker against a three-color deck that naturally runs more lands and will often be able to play around it by mid-game. Peek is your most expendable cantrip since its hand-peeking upside matters less when their gameplan is transparent — you're mainly trying to resolve and protect a Dreadnought as quickly as possible. Keep Misdirection and Thwart available as free protection spells; redirecting a Lightning Bolt away from your Dreadnought back at one of their creatures can swing the game entirely.
