Mekbuster Engineer is pretty much the foundation of the Archetype. It summons each high-level Mekbuster (and other LIGHT Machines, which already shows the semi-generic Support aspect of this Archetype) from the Deck during either player's turn and can search Mekbuster S/T on Special Summon, which is an effect that is easily obtainable.

This card is a hard support for Engineer while serving as a substitute for Engineer as well and it further follows the theme of lower leveled monsters giving more benefit and the benefit gets lower the higher the level goes. For this example: While the original summons big beaters from the Deck, Controller needs more setup to Summon a big beater although that may pay off just as well as she is treated as Engineer on the field. However, since the Archetype can support the original Engineer more than this "fake Engineer" (the last effect of this card is also a big support for the original Engineer), the original will mostly pay off more.

As the levels for the girls get higher, their effects get worse. At least for Mekbusters. Adding a big one to your hand is not that much what you want to have on a Normal Summon since you want to summon them off Engineer, however that does not change the fact that this is a good effect for desperate situations where you really need that beater for Fusion Summoning or just for it's float. The other effects of this card are rather decent, while still being restrictive supports for Engineer.

The last Main Deck girl with the highest Level therefore the worst effect, although she still has a lot of uses. First off the Attribute Change can make all your monsters any Attribute that ties in nicely with her second effect that is good removal while also triggering the big guys' float. However the cost on the first effect makes this card less viable (unless you have enough Float Targets in your Grave) and this is one of the few cards that don't support Engineer and aren't supported by Engineer.

And here we are with our first Mech! Basically the Mechs have the same theme: They can Special Summon themselves from the hand by tributing Machine/Mekbusters, have an extra trigger if they get summoned by Engineer and a float. For all of these effects, Brawler is the strongest. On Engineer Summon, it adds any Mekbuster Monster to the hand, which is good in this sense because it can also add Scavenger or another Engineer if need be and it is the only Mech to float into 2 monsters.

Wot in tarnation, is this a Codeman reference!? Ehm... well, General is a nice card for it's mulligan +1 and it's removal effect which however does counteract the usual strategy of having Mekbusters in the GY to float into. It's a decent card but not the best.

Now we're getting a little ridiculous since this card needs an Extra Deck Machine to be summoned and cannot be summoned by Engineer. However this card does still support Engineer and opens up a lot of interesting plays like freeing up the EMZ, then resummoning that Monster tributed and put another monster in the EMZ. Not much else to say about this one.

It's a Monarch! ...but actually the worst Mekbuster in terms of summoning condition and effect also being Level TEN makes it's usability as a Monarch much lower. This card in addition to an Engineer can be a nice tech in Decks that want to mill a specific Machine though. But that's all there is to Emperor. Highest Level, Highest ATK, Worst Effect.
