Even if Auto Tap is set to On, you can override it at any time in the game by entering Full Control (which you do by pressing Ctrl on desktop, or on mobile by tapping and holding your player avatar to enable or disable full control)
Decks playing at flash speed like Heliod, the Radiant Dawn can make the activated ability enough of a barrier that people wont attack you without ever even needing to activate it
Unfortunately in this expansion set, pull rates are a little more lower than the Scarlet and Violet 151 set making Pokemon Trainers have to spend more to actually get some of these most expensive cards in the Pokemon TCG: Paradox Rift expansion set like Roaring Moon and Iron Valiant which ranks somewhere in this list as one of the most expensive cards from Paradox Rift
You can see why it's here, right
Its definitely a lifegain card in 1v1 Magic where you usually start with 20 life
The set also explored the brand-new (at the time) explore mechanic, which Merfolk were heavily involved in
