Inflame

2(3) Strength can make a difference in some Elite and Boss fights, and can synergize with multi-hit cards. It's especially good with Thrash, which gains more damage from all the cards it eats. That said, Ironclad more naturally benefits from playing singular high-damage attacks in Slay the Spire 2 in my experience, and those don't care about Inflame as much. Don't assume this card needs to be in your deck when you're offered it, make sure that you're getting some value out of the scaling it provides in fights which are coming up soon.

The quintessential 'scaling' card. One copy gives you enough damage for the first Act and part of Act II, but won't be enough for the endgame. Multiple copies can work, but there are easier ways to gain large amounts of Strength. A decent early-mid game pickup.
