The big limiter of these kind of cards is they play in a similar space to Treasure Cruise and dont synergize with Cruise
However, as a three-mana Aura that does nothing immediately beyond one counter and requires attacking to scale, its vulnerable to removal and can lead to tempo loss, making it weaker than more efficient or resilient options like **Hardened Scales** (cheaper, global counter scaling), **Invigorating Surge** (instant-speed counter doubling), **Hydras Growth** (automatic upkeep doubling without needing to attack), or standalone threats like **Managorger Hydra** that grow without risking card disadvantage
Players who pick up Magic: The Gathering for the first time face an intimidating learning curve, thats for sure
