the undefeatable red pokemon card Undefeatable Red GX Black And Red Foil💥Fan Art💥 Is this card Tournament legal???

It is just a normal legendary creature which allows you to dig the top 5 cards of your deck for a potentially free big boy

Then you can +1 them to put three +1/+1 counters on a trampler or haster, like the token, or suggesting a haste and/or trampler brew

In short, he becomes a draw engine, he fills our graveyard (which is great for our Esper Zombie Tribal), and by attacking on its own he buffs our Zombies with +2/+2 (normal card draw on upkeep + his card draw on attack trigger)

Letting you reuse Treasure or tap trinkets like Food and Clues for mana is absurd, especially given how free those tokens seem to be these days
