Meowth #106, Rotom ex #126, and even sealed blisters overshadow it from a cost perspective, and considering you're guaranteed to get a card by buying a single, I'm tempted just to outright buy it instead
Metang has the Metal Maker ability, which allows players to look at the top four cards of their deck and attach any amount of Metal energy they find among those cards to their Pokmon in any way they like
Yes, it will benefit your other opponents similarly to the C17 curse cycle (Curse of Opulence, Curse of Disturbance, etc.), but it will also incentivize those opponents to send more Creatures towards the cursed player to benefit from the free card advantage (and additional damage thanks to Trample)
There are some newer cards than Etali that offer plenty of value, though, and Pip-Boy 3000 is one
The aggro deck is unconcerned with politics
