Additionally, the new Transcendosaurus archetype provides generic support for Dinosaur Monsters and introduces fans to upgraded versions of classic Dinosaur monsters like Megazowler and Frostosaurus
I want to highligh two things here
Droll & Lock Bird stops the opponent from adding a card from their deck to the hand more than once in a turn, which often stops combos before a single boss monster can be played
It either straight-up kills a creature with no counters or peels up to three counters off one
Next, why we're reverting these changes now : Ideally, reversion of balance adjustments due to format legality would happen at the same time as the format legality of these cards changesi.e., rotation
If you have two of these effects, you can even loop them as a win condition because youll never deck, just reshuffle your graveyard into your library
