For people who are still debating on who to choose between Selma and dahlia, i THINK i have the solution for your problems.
You will have to keep two things in mind.
Firstly, the room you are playing in. In survivor (t2), deathmatch, dahlia is a beast because even low damage has a place in the deck as there will surely be cards that have 7 damage or more.
If the room is elo or type 1 (up to your preference, dahlia can be used here effectively as well) Selma is the better choice. Not just because she is cheap, she has a solid 7 damage accompanied by her solid 7 power and solid +2 pillz ability. Selma is undoubtedly the better ALL ROUNDER.
Secondly, you will have to be aware of your style of play.
If you are playing Piranas, you most certainly would have at least one pill manipulator in your deck. This is where the 5* choice comes in. You should know how you can play best. With more pillz, or with less pillz.
For example: you win with dahlia and your opponent has 4 pillz while you have 7 pillz. Over here, you think if you can play nicely or not. Can you manage with such pillz? In situations like this, you DO put your opponent underpressure but you put yourself under pressure as well. If you know that this is your strength, the go with dahlia
example = You win with Selma. you have 9 pillz, your opponent has 5 pillz. here, you canfreely pill your cards, not worrying THAT MUCH about your mathematics. If you are more comfortable playing with more pillz rather than less, Selma
I sort of agree, Selma is a better all round solid card but I find myself going back to Dhalia...why? Because sh scares ur opp. way more than Selma! 2 pillz on Dhlia= either opp. overpillz (6+ pillz) or they Dr/ Put 1 pill on a weak card.
EIther way u win!
I find that Selma isnt as feared
I like Selma better for the fact that you can overpill without much fear with her. If you're down to your last 2 cards and bluffed nicely, you can pill enough to beat either of the cards your opponent has left while still having enough afterwards for your next card because of her ability. Min. 5 is a little too high to be of much use in the 3rd or 4th round I think and I like the fact that I can 2Hko with Selma.
