Draft reading signals
pack 2 pick 1, I'm committed white aggro but premium black removal keeps coming to me. splash or pivot?
Splash — don't pivot. You've got ~15 white picks banked; throwing them away mid-draft leaves you with a pile of nothing. Black removal is exactly what white aggro lacks to break a ground stall, so take it, prioritize a dual land or fixer on the wheel, and cap the splash at ~3 cards you can cast off two black sources. You'd only pivot if white had been getting cut hard — and it hasn't.
In game vs a meta deck
Standard: I'm on Dimir Midrange vs Mono-Red. turn 3, I have removal and a counter up. they curve out and pass with one card left. do I remove the creature now?
Hold it. Trading your removal for a one-drop is the game Mono-Red wants to play. You're the control deck here — their early creatures aren't what kills you, their burn and their top-end threat are. Let the small stuff through, save removal for the payoff, and race their empty hand: they're down to one card, so every turn you don't die tilts the game to you.
Deckbuilding is a splash worth it
I want to splash black for removal in my Izzet Prowess deck. how many black sources do I need for a turn-2 play, and is it worth it?
Not on turn 2. A single black pip by turn 2 at ~90% needs about 14 black sources (Karsten) — in a 17-land aggro deck that's most of your mana bending to black and choking your blue/red costs. Treat the splash as a mid-game answer instead: ~8 sources gets it online by turn 4–5. So splash it as late interaction, or skip it and run on-color removal to keep your curve honest.
