Shardless painter´s

[atopebenidorm]

I am trying a very beautiful decklist of painter´s combo with counterbalance like Jared Boettcher Invitational decklist :http://www.tcdecks.net/deck.php?id=13956&iddeck=102642

Adding Shardless agent is an innovation, It change the character of the deck. My first decklist with countertop:

3 x Goblin Welder
3 x Baleful Strix
4 x Painter´s Servant
4 x Shardless Agent

3 x Counterbalance

4 x Brainstorm
4 x Force of will
4 x Lightning bolt

3 x Grindstone

4 x Sensei´s divining top

3 x Tezzeret, agent of bolas

1 x Academy ruins
1 x Seat of synod
1 x Great furnace
1 x vault of Whispers
1 x Island
1 x Badlands
2 x Tropical island
2 x Volcanic island
3 x Underground sea
4 x Polluted Delta
4 x Scalding tarn

Side: Ensnaring Bridge x 3 pyroblast x3 pitting needle x2 Abrupt decay x3 spell pierce x2 Nihil Spellbomb x2

Another decklist more aggresive (without countertop)

3 x Goblin Welder
3 x Baleful Strix
4 x Painter´s Servant
4 x Shardless Agent
4 x Deathrite Shaman

3 x Thoughtseize

3 x Transmute Artifact
4 x Brainstorm
4 x Force of will
4 x Abrupt decay

3 x Grindstone

1 x Academy ruins
1 x Seat of synod
1 x Vault of whispers
1 x Great Furnace
1 x Bayou
1 x Badlands
1 x Volcanic island
2 x Tropical island
3 x Underground sea
2 x Scalding tarn
2 x Verdant catacombs
4 x Polluted Delta

I think this construction has many posibilities, probably a countertop construction is strongest than aggro-combo. Any ideas?, any relevant card?, suggestions?

Gamble is a good-looking card, I will try it.
