Strategy:Magic Monkeys Only

Magic Monkeys Only features the same rules as Hard Mode, but only Magic towers and the Hero can be used. The limited tower selections increase the difficulty of gameplay, but the ability to use the hero and the variety of good Magic towers make this game not excruciatingly difficult.

For purposes of clarity, the following definitions will be made for this article:

Early-game = Rounds 3-40
Mid-game = Rounds 41-60
Late-game = Rounds 61-80

General tips

The most challenging rounds in Magic Monkeys Only

Round #	Bloons spawned	Reasoning
40	MOAB ×1	The MOAB necessitates a well-prepared setup with good single-target and grouped popping power. The hero must be utilized here as well, and if not, the MOAB may necessitate many sell-and-rebuys that hurt the rest of the game.
63	Lead ×75 Ceramic ×122	The 3 tight Ceramic waves with 40, 40, and 42 Ceramics respectively pose a tall task. If placed towers perform poorly against grouped Bloons, many sell-and-rebuys may need to be performed. Doing so may create a dead-end with Round 64's rush of MOABs (including Fortified).
75	Lead ×14 Fortified Lead ×14 Fortified MOAB ×3 BFB ×6	The 6 BFBs in 3 separate packs (especially the last dense pack of 3 BFBs), fortified MOABs, and Leads (which block projectiles) require a very well-rounded defense suited for blimps and Bloon clumps. Total ability usage can make defeating Round 76's Regrow Ceramics impossible.
78	Rainbow ×150 Ceramic ×75 BFB ×1 Purple ×80 Camo Ceramic ×72	Without a solid Camo popping power or reliable decamo, the densely packed Camo Ceramics will easily break through the defense, with each Ceramic wave being even denser than those of Rounds 63 and 76.

Towers & heroes suited for most maps

Name	Portrait	Reasoning & how to use
Geraldo		If Geraldo is purchased before Round 10, Rare Quincy Action Figure can make greater than $23,000 by Round 60, allowing for the early purchase of towers that greatly simplify the rest of the game, such as Spirit of the Forest. In addition, See Invisibility Potion simplifies Camos by allowing one tower to pop all Camos on Rounds 33-58 if used on Rounds 33, 42, 47, and 53, Sharpening Stone and Gerry's Fire work well with Bloonjitsu + Shinobi army and Poplust army, Tube of Amaz-o-Glue simplifies rounds such as 63, and Genie Bottle breezes through the most difficult rounds, such as 75, 76, and 78.
Obyn		Obyn's buffs to Magic towers, especially Druids, are very useful in Magic Monkey Only. Wall of Trees is also a powerful asset, as it can tank many Bloons or several blimps and explodes to make much-needed extra money. Brambles can also take out early Camos (albeit needing some luck on multi-lane maps) and do good single-target damage, and Nature's ward totem provides good support by slowing down Bloons and blimps.
