Man, I wish I could’ve seen the look on his face when you defeated him after that…
Adding to what other have said:
There are enchantments, but only aura-like, every enchantment must go to a creature. There aren’t instants, every card is played at sorcery speed. There are secrets, though, you play them during your turn, they stay hidden until your oponent does something specified on the card, then it triggers.
In general it’s quite more simple than MTG, so if you’re familiar with that you’ll get a grasp of this very quickly. I’m finding it more fun, though, there’s no way I could se me having this much fun playing MTG over the internet against strangers.
