My poor stream community has seen about 800 versions of "the camel deck"; these used to include Echo / Second Sight mechanics, then Nightfall happened.
Games with this deck are always spectacular because everyone fails to identify the actual threat. Guaranteed, 9/10 times someone will nuke Katra first while you laugh your way to 70 Health the next turn.
But the real allure? An entire board of Flying, Echo, Warcry, Charge, Unblockable, Deadly camels with 0 Strength. Shoot for that, or you're doing it wrong. Take it from me, the #1 Ranked Eternal Player at Making Decks With Camels.
You can substitute or sideboard any card ever produced, including business and holiday cards, because camels work with literally everything. I lied. NEVER REMOVE THE CAMELS FROM A CAMEL DECK. You will be sad and also have no caravan, and probably die in a sandstorm.
Edit: Unless noted otherwise, you can always swap out any part of my decks for removal. How much removal you need will vary dramatically based on whether you're playing casual (basically none) or tournament (basically half), and the type you use will have to depend upon the biggest threats in-meta--with rare exceptions, removal is the part of the deck it makes the least sense for me to specify.
