Instant Destroy target artifact or enchantment
This is one of them, and it's a doozy
Every time you dig a little deeper into your deck with one of those mechanics, you just straight-up draw a card afterward
Enrage is one of my favorite mechanics and made me fall in love with Dinosaurs, giving them a unique personality instead of just being "Dragons but without wings." I'm a bit bummed that enrage didn't show up heavily in this set, but I'm over the moon with Wayta's design: at just 3 mana she doubles the value of all your enrage triggers, AND she can trigger your enrage stuff for one mana, AAAAND she can act as repeatable removal having your bigger creatures fight opposing one for 3 mana
In tempo shells with lots of cheap removal, cantrips, and counterspells like Daze to help trigger Katara and protect her, she can easily bury the opponent in card advantage
