One of my first casual decks was black/white removal. It was a random potpourri of evasion, bombs, and (obviously) removal--stuff like Stormfront Pegasus, Deathless Angel, and Doom Blade. I liked the aesthetic (aren't those cards gorgeous and flavorful?) and the strategy this deck provided; you do early damage with a fleet of pegai, doom blade any big threat, and drop an angel to finish the game.
The deck featured here attempts to follow this same game plan, but with a lot more consistency and synergy. I've found this to be a very fun casual deck, and it's extremely budget-friendly. If you are interested in finding a non-budget competitive, established deck with similar ideas, I'd recommend checking out Death and Taxes or Deadguy Ale. Another option which I am currently exploring is Azorius Titan (possibly a mono white variant). Below is a short primer on what this deck does.
Korzhov
Every creature has an ETB effect (mostly removal). These effects can be repeated with bounce and reanimate abilities on double-duty cards like Orzhov Charm, Kor Skyfisher, and Sun Titan. All the non-creature permanents also have ETB effects, and are at CMC >=3 so that Sun Titan can fetch them back.
The Kor of the deck
4x Kor Aeronaut
4x Kor Skyfisher
These are the replacements for Stormfront Pegasus. They enable ETB combos, and the Aeronaut kicker can provide a nice finisher with Sun Titan or even Skinrender. The Aeronaut also benefits the most from bounce to hand effects (as opposed to flicker), and does not work when reanimated with the titan.
Removal
Here's the pile of removal I added. I wanted cards that could deal with many scenarios, and was especially interested in cards that exiled or provided a body. This is a pretty versatile and large pool of control.
Doom Blade:
4x Orzhov Charm
4x Bone Shredder
Exile/anti-indestructibility:
3x Journey to Nowhere
3x Oblivion Ring
3x Skinrender
Hand Disruption:
4x Tidehollow Sculler (anything)
3x Sin Collector (inst/sorc)
List of combos
Here's a short list of how the ETB effects come together in 2-card combos.
Sun Titan + Bone Shredder
" " + Sin Collector
" " + Oblivion Ring (if it was removed/discarded)
" " + Journey to Nowhere (same)
" " + Kor Skyfisher (free bounce!)
" " + Tidehollow Sculler
" " + Kor Aeronaut.
Kor Skyfisher + Sun Titan
" " + Skinrender
" " + Scoured Barrens
etc.
Orzhov Charm + any creature. (Note: Tidehollow Sculler + Orzhov Charm = permanent exile.)
Kor Aeronaut kicked + Sun Titan
" " + Skinrender
" " + Sin Collector
" " + Tidehollow Sculler
to get those non-evasive butts in the air.
