Eowyn, Shieldmaiden lets you build an army of token creatures with trample and haste, and turn those into card advantage, while also being a 5/4 with first strike in her own right
Going past the one time is the real gold here, and I think the ceiling for card advantage could be quite high depending on the deck
The premium is in complete sets, and that premium depends on continued collector interest in the format
Rather, a second "reflexive" ability triggers when you discard a card this way
Lots of people grew up with the Wizards Of The Coast era of Pokmon and the thrill of opening those packs again, just like they did as kids, brings back lots of joy and excitement for people
