315.5b Face-down conspiracy cards have no characteristics
Lantern was reprinted and saw a quick drop and then immediately rebounded as it was only included in 1 of the 5 decks and players needed far more than got printed
For example, an aura-based EDH deck would run Winds of Rath to destroy everything but their creatures, allowing them to leverage the board wipes as a catch-up mechanism and finisher
I go over a few different ways to do it, depending on what you want from your custom cards
The deck starts by casting efficiently costed creatures with strong secondary abilities including Claim Jumper (land fetch), Finneas (+1/+1 counters, draw), Ghired (creates tokens), Jacked Rabbit (rabbit creature tokens), Mirror Entity (increases base power/toughness), Warren Warleader (rabbit tokens, anthem effect), etc
You can't use this effect to assign some of the creature's damage to a blocking creature and the rest to the player, planeswalker, or battle it's attacking
