Not so fast my friend! The limit of using Burst Core is 2. You already used it 2 times. Sorry. Also, the limit to Omega is 3 and you already used it three times. So you can't use those abilities anymore.
Go Nemus!
380gs plus
Me: 380+390=770
You: 860
Triple Ability Activate!
Reflection Boost: Allows Scorpion to decrease your opponent's power level by 300 Gs.
Trick World: Available once, every three brawls. Reduces your opponent's current power level to 100 Gs. (BANNED IN TOURNAMENTS)
Shade Cocoon: Allows your Nemus to shut down your opponent's future Ability cards for this turn. Special Abilities and Fusion Abilities are excluded from this effect.
Me: 770
You: 0 And you can't use any ability cards, and your Omega and Burst Core abilities aren't available anymore since you already used their limit.
