If we're talking about having fast mana in the deck, then Ancient Gold Dragon is just an auto include. 5 and 2 White for a 7/10 Dragon with Flying and whenever it deals damage combat damage to a player you can make up to 20 1/1 blue faerie dragon tokens. It's a chunky creature that can get out of control extremely quickly and basically forces your opponent to answer it. It's about $15.
If playing mono-white I'd recommend considering Martyr's Cry as card draw. I consider Land Tax & Tithe to be card advantage, not Ramp. Wrath of God was one of the first sweepers I pulled from one of the first packs I ever added. I find at this point that I prefer effects that don't specifically destroy creatures - Farewell (of course), Hallowed Burial, and Sunfall, for start. I'm also a fan of Cleansing Nova as it can take care of Enchantments & Artifacts. During the Tutors section you called out Academy Rector as Academy Manufactor.
Martyrs Cry is an interesting card. Exile all your white creatures for a big burst of card draw. Sorcery speed lets it down a litte due to the type of effect it is. If you have lots of white creature tokens could net you a lot of card draw. the problem is if you draw it late game and you need your creatures to defend.. it becomes a dead card unless all players are running mono white decks... :/ Exile creatures is great on sweepers as like mentioned gets round graveyard shenanigans ;) yeah I miss spoke but i got the right card on screen haha. sorry about that >.
@@Spencer4686 Martyr's Cry is far from perfect or consistent. I view it as part of casting a board wipe. I tend to play more boardwipes than I should, perhaps.
