A fun idea which works pretty well online for a Gladiator Beast deck.
I came up with the idea at the same time that I was learning about Mekk-Knights and then I saw
a deck on yugioh-card which had a few Mekk-Knights in it, and thought I should try the Mekk-Knight engine here.
World Legacy's Secret is a pretty good card that can also be used to recycle
Gladiator Beast Tamer Editor, other than providing monster negates when you have a Mekk-Knight. The Mekk-Knight engine also helps with the age-old problem of Ashing a
Rescue Rabbit or a
Test Panther and stopping you in your tracks. Aside from that, it provides access to Number 38: Hope Harbinger Dragon Titanic Galaxy and Dingirsu, the Orcust of the Evening Star.
Yes, I know that not everyone is comfortable playing about 40 cards, but I've gotten used to running Glads at 45 cards. This is a deck that I want to try in real life, the only cards that I don't have yet are
Mekk-Knight Blue Sky and
Mekk-Knight Purple Nightfall.
