Trigger Patterns

Use this skill when the user asks about:

• MTG card prices, values, or price history ("What's Sheoldred worth?", "How has Force of Negation trended?")
• Deck building or deck help ("Build me a Modern deck", "Help with my Commander deck", "Here's my decklist")
• Card recommendations by ability, color, type, or budget ("Find me black removal under $5")
• Format legality ("Is this legal in Standard?", "What's banned in Modern?")
• Sealed product evaluation ("Is the MH3 box worth buying?", "What's the EV of a collector booster?")
• Card investment or finance ("What cards spiked?", "Reserved List picks", "Arbitrage opportunities")
• Card strategy or evaluation ("What role does this card play?", "Why is this card good?")
• Budget alternatives ("What's a cheaper replacement for X?")
• Mana curve or deck analysis ("Is my curve too high?", "How many lands do I need?")
