MANAHIVE

Invasion of Ergamon has unique attributes: it's a red-green Battle — Siege, makes a Treasure, and provides card filtering. There are currently no exact equivalents among Battle cards sharing its color and utility. Closest red-green Sieges with somewhat related effects (but not equivalent) are:

• Invasion of Kaldheim (red): Exiles cards then lets you play them.
• Invasion of Zendikar (green): Ramp effect, gets basic lands.
• Invasion of Tarkir (red): Deals damage to creatures/planeswalkers.

Reason: No other current Battle — Siege exists in both red and green that creates a Treasure token and provides looting/card filtering. Each Battle card is unique in ability so far.
