I played Madolche now for two months and discovered several facts about them. However I do not want to make this a "Madolche Guide".I want to present you my thoughts about their two main engines.
It is the T.G and the Key Mouse engine. I am pretty sure that people who played them saw that card, but never tried to make a Madolche deck around it. If my following theory will be wrong, please feel free to correct me :3 Lets start:

T.G Warwolf
+can be special summoned from the hand
+searches T.G Striker
--------------------
= [2+]

T.G Striker
+can be special summoned from the hand
+tuner
+searches T.G Warwolf
--------------------
= [3+] + [2+] = [5+]

Key Mouse
++searches itself and all beast Madolche
+set ups easily Hootcake plays
+tuner
--------------------
= [4+]

Mimimic
++ can be special summoned from the hand almost at any time
--------------------
= [2+] + [4+] = [6+]


Speed calculations:

T.G Warwolf: +
T.G Striker: +
Key Mouse: o
Mimimic: +

T.G Engine: Speed = 2+
Mouse Engine: Speed = 1+

Overall:
T.G Engine: Speed/++/2/100%/[5+] = 7
Mouse Engine: Speed /+/1/50%/[6+] = 7

Conclusion:
T.G Engine: Gives you more speed. However you lose flexibility, because of T.G Warwolf. In order to use him you must make certain plays and that is not good.

Mouse Engine: Gives you flexibility. However you lose speed.
