Custum Yugioh Cards:Mercury Set (Unfinnished)

lately ive been realy getting back into playing yugioh,eversince i met some new friends at my town's library,whome are also devoted players...and it sparked the insperation i needed to start designing my own custum yugioh cards.

these cards were all created useing Yugiohcardmaker.net

t(many consiter this not to be legidiment art,however all these cards depict artwork i made myself...so i consider this fan art at least.

................................
my mercury set revolves around,as you problubly noticed,creatures who are made of liquid Mercury...whose relitivly low stats are made up for by having powerfull effects. thier major stratigy is going to target your oponents ability to use cards with eny sort of specail effects. (tho only one of these cards has such an ability,but like i said it isint finnished)

so eny suggestions on new cards i should create,id love to here them
