Hi guys! I'm new to the forum but I'm an old Magic player. Actually I haven't played for several years, but I recently thought about completing my old and overlooked decks. One of them is a mono-white flanking deck. At the moment, it's a mess. This is what I came up with:
Personally, I would cut the bigger creatures and anthem effects for more 2-power creatures and run four Dusk // Dawn. Dusk spares all of your creatures, leaving your opponent with just their little guys against your flanking knights, and Dawn is a great late game card advantage engine.
Update: I made some other changes to make the mana curve more balanced. The main change consists of 4 Sinew Sliver, which can make the combo even more powerful. Then I replaced Prison Term with Nemesis Mask as a secondary combo with a multi-flanker.
