Cheetah Racer Sogdo (Korean for "speed")
Level 4 | WIND | Beast-Warrior | Tuner | Effect
(1) When this card is Summoned: Place 1 Speed Counter on all "Cheetah Racer" monsters you control. (2) Once per turn: You can send 1 "Cheetah Racer" monster from your hand to the GY; place a number of Speed Counters equal to the sent monster's Level on "Cheetah Racer" monsters you control.
[No, I did not design this because of the September challenge, BUT I think I might add it to the thread as legacy support, which will count as fair game. I would advise you just sticking to the original idea though.]
I'll provide another one that's generic; still cheetah based, but yeah.
