While the original might have been upstaged by its newer, flashier March of the Machine version (read on for more on that), Etali, Primal Storm remains a classic Dinosaur creature that can capably steal cards and wins from foes out of nowhere if you hit the right stuff from their libraries
Cards like Primevals' Glorious Rebirth, Urza's Ruinous Blast and Karn's Temporal Sundering are powerful but require a legendary creature or planeswalker on board to cast
Competitive players might decide to add the new Charmeleon [Paldean Fates] into their powerful Charizard ex [Obsidian Flames] deck because it has a built in Bench Barrier Ability, which would prevent it from getting KOed from Radiant Greninja [Astral Radiance] attacking
This is implied by the attack and defense icons
Not every deck that can run Kricketune will run it, but decks that do will likely include 2 copies of the card, in addition to 2 copies of Kricketot, the Basic Pokmon
