reflect card yugioh Infernity Reflector [TSHD-EN068] Common may be 1st or Unlimited Edition Yugioh: Scuthm Reflect by DarkTidalWave

There's also combo potential with cards like Triskelion: if you can first get a +1/+1 counter on Daggertooth then you can ping it with Trisk, proliferate both the Daggertooth and Trisk to add another +1/+1 counter to each, then repeat infinite times for infinite proliferate and an infinitely large Dino

Demand and supply comes together to form the market price, not rarity

Allowing players to trade their duplicates for pack points would solve this problem and make all booster packs worth something, even if the loot is bad

Id say theres about a 25/75 split on how useful the sacrifice effect is versus the token generation, but it all comes together for a highly synergistic engine
