Inundation (Casual)

Cheap white creatures and more cheap white creatures have always been a winning combination, and the Inundation deck is no exception to the rule. You should play your creatures as quickly as possible and attack early and often. With this deck, you have to play aggressively. Attack when you can, defend when you must. You may lose a creature or two when you attack, but keep up the assault as long as you can deal damage to your opponent. The first to deal 20 damage wins, and this deck does that faster than most.
Even if your opponent manages to set up a defense, this deck still has some effective weapons. Creatures with flying can often get through for the last few points of damage, and protection from creatures makes Beloved Chaplain and Commander Eesha impossible to block. Battle Screech gives you lots of 1/1 flying Birds in a hurry. After you play it once, you can tap your two new Birds and another creature to play it again with flashback. And with the enchantment Unquestioned Authority, you can give your best creature protection from creatures and draw a card in the process.

The deck also has some tricks to save your creatures again and again. Shelter and Benevolent Bodyguard can each rescue a creature from imminent destruction by giving it protection from the color of your choice. Prismatic Strands is even more versatile. If your opponent attacks you with a bunch of creatures, expecting to win, you can use Prismatic Strands to save yourself and then win with a counterattack. You can use protection effects to get an attacker through, too: If all available blockers are the same color, give your creature protection from that color. Your opponent won't be able to block.

Most decks that rely on small creatures have problems with cards that can get rid of multiple creatures at once, and the Odyssey block is full of cards that can really ruin your day. Adding more Prismatic Strands and Shelters will help the deck against spells like Shower of Coals and Swelter. If you're worried about other mass-removal spells, like Kirtar's Wrath, you may want to splash green for the Judgment cards Genesis and Nantuko Monastery.[2]
