Mechanically, this can be easily navigated the instants and sorceries will likely depict feats of battle or preparations, much like some of the cards from grittier sets like Khans of Tarkir
Emrakul, the Aeons Torn isn't easy to get into play through mana, but spells like Summoning Trap, Through the Breach, and Sneak Attack can and have been used to cheat Emrakul into play for far fewer mana
#6: Red Elemental Blast/Pyroblast Speaking of the best sideboard cards of all-time, Red Elemental Blast and its nearly identical analog, Pyroblast, are extremely high on the all-time list, thanks to whole Counterspell + Maelstrom Pulse for one-mana thing, and in a color that doesnt get access to such things but greatly appreciates them
Bad Stone Rain Variant
Even if the Curtains die to a Lightning Bolt or Unholy Heat (rarely with delirium on Turn 2) after blocking the Monkey, they still blocked the Monkey before trading, when the typical auto-loss pattern is having your Turn 1 creature die to removal on the spot while your opponent gets a free Treasure and card flip
For a start, we hope theres now the critical mass of Madness cards and enablers to make a real deck based around them
