Very Short worth a read!!
Hey so I've noticed SCG is sometimes slow on phones and its a pain for trading. MTG familiar or whatever it is just sucks. I found a nice alternative. It can handle foils it uses SCG as fair as I can tell. Will do any edition and you can type in the name wrong but as long as its close it'll pick it up. Here is the link. Also it is free if you can follow the instructions.
The whole ARK42 site is cool by the way showing price histories of cards.
I see some people asking about card rulings as well and this next link is an online chat where judges are always online to answer questions. They sometimes take a couple minutes but very good at explaining
