The only Fusion Monster this works with is at least margianlly useful.

Topaz Tiger and Sapphire Pegasus (#7) should be your choices because they are the strongest.
Ancient Millennium (LED2-EN038)
Rainbow Bridge
SPELL / Normal Spell
Add 1 "Crystal" Spell/Trap from your Deck to your hand.
(Ultra Rare)
Rating: 1 out of 5
Would be good if the other support (#45) was any good, and this can't even get all of it.
Ancient Millennium (LED2-EN037)
Rainbow Overdragon
LIGHT / Fusion Monster / Level 12 / ATK 4000 / DEF 0
(Dragon / Fusion / Effect)

7 "Crystal Beast" monsters

Most of the Crystal Beasts can provide a relatively decent boost, but this isn't great.
Ancient Millennium (LED2-EN033)
Cross-Dimensional Duel
TRAP / Normal Trap
Target 1 "Ancient Gear" monster you control; banish it. During the next Standby Phase, return that monster banished by this effect to the field, and if you do, its ATK becomes double its original ATK until the end of that turn. If 1 or more "Ancient Gear Golem" or "Ancient Gear Golem - Ultimate Pound" you control would be destroyed by battle or card effect, you can banish this card from your GY instead.
(Super Rare)

It's risky, but then you'll have a temporary powerhouse that isn't destroyed later on.
Ancient Millennium (LED2-EN032)
Ancient Gear Fusion
SPELL / Normal Spell
Fusion Summon 1 "Ancient Gear" Fusion Monster from your Extra Deck, using monsters from your hand or field as Fusion Material. If you use "Ancient Gear Golem" or "Ancient Gear Golem - Ultimate Pound" you control as Fusion Material, you can also use monsters from your Deck as material.

This is like really bad Yu-Gi-Oh fanfiction. The two don't really mesh well at all.
Ancient Millennium (LED2-EN023)
Ojamatch
SPELL / Quick-Play Spell
Send 1 "Ojama" card from your hand or face-up from your field to the GY; add to your hand 1 "Ojama" monster with a different name and 1 "Armed Dragon" monster from your Deck and/or GY , then, immediately after this effect resolves, you can Normal Summon 1 of those monsters.

A fusion of two pretty potent monsters, but it's about as unlikely to be played as Dark Sage. (#96)

Practically lone support for Barrel Dragon, and it's not even ideal outside of that.
Ancient Millennium (LED2-EN016)
Heavy Metal Raiders
SPELL / Field Spell
The first time each DARK Machine monster you control would be destroyed by battle each turn, it is not destroyed, and if you took battle damage from that battle, it gains that much ATK after damage calculation, and keeps that ATK gain as long as this card is on the field. Once per turn, if a monster you control that was originally a DARK Machine destroys a card(s) on the field by battle or by card effect: You can Special Summon 1 DARK Machine monster from your hand.
(Super Rare)
Rating: 1 out of 5
Protection from just 1 attack isn't going to cut it as so few DARK Machines are even remotely strong.
Ancient Millennium (LED2-EN015)
Desperado Barrel Dragon

(Machine / Effect)

If a face-up DARK Machine monster(s) you control is destroyed by battle or card effect: You can Special Summon this card from your hand.

A card coming up would support this, but this is only slightly stronger than the original. (#126)

BM-4 Blast Spider
DARK / Effect Monster / Level 4 / ATK 1400 / DEF 2200
(Machine / Effect)

Searchable, has high DEF and a mini Ring of Destruction effect, but you're down a monster too.
Ancient Millennium (LED2-EN010)
Corrosive Scales
TRAP / Normal Trap

Restrict (#195) can only do it during your turn so this'll help patch that vulnerability, but it could be better.
