Magic the gathering: im sort of new and have a few questions about my blue deck?

Question

i know blue is good with artifacts [i use afinity for artifacts] and deception/trickery [sp] but im sort of new at this so how exactly does the trickery and stuff part work? can you give me an example of how blue uses trickery? thanks =]

oh..and i like to use walls too because i have a card that lets me bring back any artifact creature from my grave once per turn so i block with walls then just keep bringing them back.

so any good walls for blue or black? pref. with regenerate.
and just any blue cards i should look out for?

Answer 1

About the trickery part here is an example: In masques block there was a wall called Stinging Barrier, 0/4 with : U, tap: stinging barrier deals 1 damage to target creature or player.
People used to enchant it with Charisma (UUU, Aura, enchant creature, whenever enchanted creature deals damage to other creature, gain control of that creature), and used to steal creatures once and again. In Urza's Block the 'steal' card of choice was Gilded Drake. Magical Hack is also a trickery card because changes color and or land type on other cards.
About Blue/Black walls, here's a small list:
Stinging barrier, wall of bones, wall of tears, wall of deceit, wall of wonder, carrion wall, etc

Answer 2

You could use Wall of Vapor. It's a 0/1 wall creature, but with: Damage dealt to Wall of Vapor by creatures it blocks is reduced to 0.
This will work well against a green deck, but can be killed by cards that will do damage outside of combat. Creatures with trample will still do damage to you.
Wall of Air is a normal 1/5 wall creature.
Wall of Water is a 0/5 wall creature with: U +1/+0 until end of turn.

I don't know if there are blue cards with regeneration, but you could use cards like Unsummon or Snap to return it to your hand.
