how to tell a pokemon card is first edition If Real 1st Edition Base Set Cards:

I think an Egon / Throne of Death plan will make it easier to keep Egon around, but there are easier ways to self-mill in Black without jumping through all those hoops

Each time a new set approaches, the writers of magicthegathering.com get to do a couple weeks of previews, showing off the new cards before you can see them anywhere else

Nissa of Shadowed Boughs, aside from being Golgari, also features a Landfall trigger that gives her an extra loyalty counter

Obviously, if you have information, thats a different story, but if all you know is that you are playing Legacy, Brainstorm is typically the move

Its a nice fit in grindy midrange decks, or zombie/outlaw decks
