ninjutsu mtg cards Ink-Eyes, Servant of Oni - Single Card MTG Best Commander Ninjutsu staple

He reduces the cost of your creatures based on how much life your opponents lost

The card allows you to shift gears from being purely aggressive to biding your time, and creates interesting tension around combat rather than a simple determination of whether to use a removal spell on one creature

None of the common 2-drops attack especially well into these, though decks like RW might be able to punch a hole with pump spells like You're Not Alone and Haste Magic

Not your run-of-the-mill Planeswalker or your foil Mythic Rare pulls

This lets you cast things outside of your color identity in red for Commander without needing to actually cast the spell, and you'll be left with a 3/2 dork to block and kill or trade or save you from a lethal attack and you can exile sorceries and cast them at instant speed

I almost included Hunters Prowess on this list out of some misguided attempt to not seem overly critical of the deck
