Mardu No EtB (Modern) [Révision 18]

Orb/Sundial + Big Sticks = Profit

Main Priority: Getting an Orb or Hushbringer, then cast the creatures. It's not always a bad idea to cast these creatures without the orb or the faerie (for example, Kroxa still gives you something when cast without orbs and can be cast again later), but most of the time is less than ideal. At least it's not Eater of Days.
The rest of non-creature cards are there to keep any threats at bay and obstacles away, paving the way for your big monsters and keeping you safe while you stablish your board.

Possible improvements and tweaks:
-Thoughtseize over IoK (moving Iok to sideboard/not replacing Iok completely due to loss of life)
-Better mana base (i.e fetches), which would leave some more space to build the spells (more slots, more creatures, more removal...) This list is just a starting point for a "budgety" build.
-Other removal options can be considered: Terminate, edict spells against hexproof... whatever you fancy.
