Double Rainbows are the only Double Bloons capable of OTKing an opponent without health buffs, assuming they lack Defenders, shields, or active Adora passive. So, they're a good candiate for triple Quick Ready when combined with Quincy Action Figure for spare gold in a single turn.
Amelia with a Double Rainbow card and three Quick Readies achieves the same result while costing only 20 Gold. Prepare an Act of Power in reserve, send the Double Rainbow, 2x Quick Ready with the discounts from 2x Act of Power, and use the final Quick Ready.
The Round 21-22 storm Double Rainbows can receive three Quick Readies without needing any special setup besides reaching the gold cap, although depending on deck waiting for the round 31-32+ Double Ceramic Bloon waves, then using Quick Ready followed by Double Trouble on the healthiest 1 delay Ceramic, may be more effective.
If the opponent lacks any screen clears such as Thunder Druid and Super Monkey Storm, Double Rainbows combined with lots of standard Large Bloons will pressure the opponent to focus on the Double Rainbows first.
Double Rainbows have 2 charges and cost 10 Gold, the most potential Bloontonium of a single bloon card (excluding very specific Bloontonium Gas Bloon scenarios).
