How to Use Thundrax
Thundrax should occupy the early tutorial or first roster slot: teaching a clean role before replaceable upgrades arrive. A strong pairing is Brimstone, because it gives the lineup a different stat angle while Thundrax focuses on HP. If the choice is between Thundrax and Mordraxis, start by comparing HP 5 against 4 instead of choosing by rarity alone. Because Starter cards are role teachers, use the page as a benchmark when judging your first pack pulls.
Strengths
- HP 5 is the page's clearest signal, giving Thundrax a real battle identity instead of generic rarity value.
- DEF 5 is high enough to act as a tie-breaker when comparing it with nearby cards.
- Thundrax has a compact spread, so it is easier to use as a flexible fourth slot without creating a glaring weakness.
Weak Spots
- SPD 4 is the number to protect. Opponents that punish turn tempo can make Thundrax feel weaker than its headline stat suggests.
- Starter cards are intentionally replaceable. Once your collection grows, compare the role before keeping it from habit.
Developer Battle Read
Developer battle read: Thundrax is a starter teacher, not a blank starter card. Its HP 5 and DEF 5 point to teaching a clean role before replaceable upgrades arrive. The first teammate I would test beside it is Brimstone, because that pairing reduces the pressure on SPD 4. I would compare it directly with Mordraxis before spending duplicates, since that shows whether Thundrax's HP lead is actually needed.

Avoid it when
Avoid forcing Thundrax into teams that already have enough staying power but still expose SPD 4. If Brimstone or another support card is not available, wait before locking it in.
Progression note
Thundrax should not be treated as a fusion target. Use it to learn the role teacher role, then replace it once regular cards cover the same job.
- Starter Teacher: use Thundrax to teaching a clean role before replaceable upgrades arrive. This is strongest when the rest of the team is not asking it to cover SPD alone.
- Team shell: pair with Brimstone when you want Thundrax's HP to matter without sacrificing coverage on SPD.
- Comparison check: if Mordraxis is available, choose based on whether your next fight needs HP or DEF more.
