GBY Towship Tempo(updated in February 11,2019)
I love this architype,and I have been studying for what is best list since 2017.
So this list is the one of my answer.
You can play this deck as both midrange and control. It´s so flexible deck!
If your opponent´s deck is control deck(e.g.B reaver,GY sacrifice,etc…),you should play midrange or rush plan because you must finish game quickly.
On the other hand,if opponent's deck is midrange,you can choose quick game or long game(i think long is often better against midrange).
Towship is always best opener because It can be very good double collecter(without Destructive Volly monkaS ).
If you assure your collect line,you can choose aggresive play or passive play.
Do you want some buff cards in this deck?It's true.but Command is neccesary against Library.and Humbling can be used in 3 turn if you summon Herald or Towship in 2 turn.so buff cards can't be taken this deck.
Kaios and Shozen are really good legendaries,and Frog-tosser is op.so you should often put special lands every turn until turn 5;you can put a 6th special land whenever you want.
Laya was changed to third octopus because she can't play turn 3 now.
And I discovered celestial tower is very good in this deck.
Let's enjoy with it!
