Thank You for Your comment!
Tideshaper Mystic is great option, I'll add it later.
Trait doctoring is not. We are not carrying anything like
invisible stalker, or anything that would strike at any point. And "end of turn" is not what we like in this sorcery - without ciphering we need 1 more extra blue to punish 1 more land, that's not the point.
Then, I have written that 2 Islands are necessary because they are. Against RDW or other aggro we have to be really careful about our life pool, because we will probably bleed it away very quickly. It's better to lose 1 life from fetch, and then lose 1
Island for a greater cost, if it is our last hope, without blue mana on board, as it could happen, so we can't search for
mountain.
Thank You for Your suggestions. I'm looking forward to Your response
