If you'd like any suggestions or comments here they come:
The deck would be more effective with fewer creatures and more pillars. Most of the time you will be left with dragons in your hand you cannot afford to play.
Deja Vu are not very powerful unupgraded and without buffs, as they will be blocked by any shield blocking 1 damage, killed by fire buckler/thorn carapace and pretty much any CC, and 2 damage per turn for 2
, one card, and 2 turns isn't much of a deal.
Of course, you can use them to add some flavor and originality to your deck, but it won't be very effective.
The deck might benefit from a single Eternity or Procrastination, although they are not necessary and would be useless against any deck with permanent control, so I guess the deck is good enough without these.
Replacing half of the pillars with pendulums would help against earthquake decks.
If you want to keep your deck original, but more effective, I'd suggest:
5rg 5rg 5rg 5rg 5rg 5rg 5rg 5rh 5rh 5rh 5rh 5rh 5rk 5rk 5rk 5rk 5rk 5rm 5rm 5rm 5rm 5rm 5rm 5t2 5t2 5t2 5t2 5t2 5t2 5t2
Of course it's just a suggestion, so don't think I'm bashing your idea or anything, any deck is good as long as you like to play it ;]
