How to Use Stonarax
Stonarax should occupy the stable middle slot: surviving pressure while contributing enough damage or tempo to matter. A strong pairing is The Singularity, because it gives the lineup a different stat angle while Stonarax focuses on HP. If the choice is between Stonarax and Umbrathrax, start by comparing HP 30 against 30 instead of choosing by rarity alone. When duplicates arrive, fuse only if this card is already solving that same battle job in your active lineup.
Strengths
- HP 30 is the page's clearest signal, giving Stonarax a real battle identity instead of generic rarity value.
- ATK 22 is high enough to act as a tie-breaker when comparing it with nearby cards.
- The HP lead is large enough that Stonarax should be chosen for that job, not as a generic filler card.
Weak Spots
- SPD 13 is the number to protect. Opponents that punish turn tempo can make Stonarax feel weaker than its headline stat suggests.
- Stonarax leans hard into HP, so it can be redundant if your team already has that same specialist role.
Developer Battle Read
Developer battle read: Stonarax is a durable bruiser, not a blank epic card. Its HP 30 and ATK 22 point to surviving pressure while contributing enough damage or tempo to matter. The first teammate I would test beside it is The Singularity, because that pairing reduces the pressure on SPD 13. I would compare it directly with Umbrathrax before spending duplicates, since that shows whether Stonarax's HP lead is actually needed.

Avoid it when
Avoid forcing Stonarax into teams that already have enough staying power but still expose SPD 13. If The Singularity or another support card is not available, wait before locking it in.
Fusion note
Stonarax can grow toward level 5 with a 50-point cap. The first meaningful checkpoint is around 11 total copies or points, so spend duplicates only if this durable bruiser remains part of your main battle plan.
- Durable Bruiser: use Stonarax to surviving pressure while contributing enough damage or tempo to matter. This is strongest when the rest of the team is not asking it to cover SPD alone.
- Team shell: pair with The Singularity when you want Stonarax's HP to matter without sacrificing coverage on SPD.
- Comparison check: if Umbrathrax is available, choose based on whether your next fight needs HP or ATK more.
