On the other hand (as I mentioned a moment ago), I don't think Wizards can reprint the fake-card problem away
Talisman of Resilience , Reliquary Tower , and a Forest can all go too
The Bridge Cycle I love Darksteel Citadel and it gets played in decks outside of artifact themes because it cannot be destroyed by Armageddon or similar mass destruction, as well as Wasteland and Strip Mine proof, which is very valuable in metagames that care about LD and run it in numbers
You also want to shave a small part of each of the three sections instead of boarding out a number of cards in any given section or else the deck wont be functional
and because Limited play is almost always won on the back of creature combat, finding the opportunities to trade one creature, removal spell, or well-placed buff for more than one creature will pay off dividends
This allows you to build a pillow fort or assemble a combo to win out of nowhere
