Hi there. This is a short Pokemon TCG post. The cards covered here are Antique Cover Fossil, Tirtouga & Carracosta from Stellar Miracle.
From the Pokebeach.com article it is expected that Japan's Stellar Miracle would be a part of the international set Stellar Crown with a September 13, 2024 release.
Antique Cover Fossil
This card is needed in order to evolve into Tirtouga. You play this Trainer card as if it were a 60HP colourless Pokemon. The ability does prevent effects of attacks used by opponent's Pokemon. This is good against attacks that places damage counters as placing damage counters from an attack is an effect.
Tirtouga
Tirtouga is a Stage 1 100HP Water Pokemon that evolves from the Antique Cover Fossil. For two water Energy the attack does 70 damage along with a Switch from Active spot with one of your Benched Pokemon.
In the current F, G, H regulation format it is easy to search for Water Pokemon with the Irida Supporter card but energy acceleration for Water is not really available outside of Baxcalibur. Baxcalibur does take up deck space as it is a Stage 2 Pokemon.
Carracosta
Carracosta is a Stage 2 160 HP Water Pokemon that evolves from Tirtouga. It is the final evolution of the Antique Cover Fossil. The ability allows your Pokemon's attacks do 30 more damage to the opponent's Active Evolution Pokemon.
The attack of Tidal Wave costs 2 Water Energy and does 150 damage. A bit of generic beatstick attacker if you ask me. I am not sure if this would be that playable from a competitive standpoint.
Thank you for reading.
