New players can pick them up quickly, while experienced players can tune them for higher power levels
Some examples: Swords to Plowshares, Teferis Protection, Chaos Warp, Great Train Heist (or other Spree cards, you pay extra costs but can go wild), Akromas Will, Deflecting Swat, Wear/Tear, and my personal favorite, Reprieve
If youre worried about build time (which is usually about 50 minutes), you can mitigate time anxieties by having a baseline done early (i.e., I know Im playing UB because I have Edgar, Sephiroth, Odin, and Ultimecia, Time Sorceress, but should I splash red for anything?)
