If I Knock Out my opponent's Active Pokemon with Wo-Chien's "Entangling Whip" attack and take my last prize card but also discard the last cards in my deck, do I win or lose because I have no cards left in my deck?
You win. You lose if you can't draw a card at the start of your turn, but since you took your last prize the game ends before that happens.

If my opponent put a Stage 1 Pokemon directly into play using Tatsugiri ex's "Cinnabar Lure" attack, and I use Paldean Tauros' "Spirited Tackle" attack while that Pokemon is Active, would it do 90 or 180 damage?
It does 180 damage. Although the Stage 1 Pokemon is not an "Evolved Pokemon" in this scenario, it is still considered an "Evolution Pokemon" (Stage 1) that meets the requirements for Spirited Tackle.

If Pikachu ex has full HP and a Lively Stadium is in play, and Roaring Moon ex uses its "Calamity Storm" attack and discards the stadium, will Pikachu ex's "Resolute Heart" Ability prevent it from being KO'd leaving it with 10 HP remaining?
No, it won't. Calamity Storm does 220 damage and that many damage counters are placed onto Pikachu ex, so it no longer has full HP at this point due to Lively Stadium and the "Full HP condition" is not met in order to trigger Resolute Heart; then the stadium is discarded, returning Pikachu ex's maximum HP to 200, and therefore Pikachu ex is KO'd. However, if Calamity Storm does 230 damage (for example, if Roaring Moon ex has a Vitality Band attached), Resolute Heart would work; the attack places 230 damage onto Pikachu ex, thus meeting the "Full HP condition" in order to trigger Resolute Heart; then the Stadium is discarded, and Pikachu ex survives with 10 HP remaining (190 damage on it).
