Both require tricks, they are in the guide
Scorpio has purify, but not many.
In general, the purifies won't come if you don't over use SoBr
So, stop playing SoBr once the combo is secure, except for clutch pulls, this reduces it's chances of using purify.
Additional things
If you have a good starting hand.
1.) Don't worry about initial damage, SoSa before Sundial, not the other order.
If you have a traditional start. This is what I normally have and is a persons primary trick.
2.) Play Sundial and SoSa at the same time when you SoSa.
(Let him heal you, Dial expires, heal above 40, repeat)
If you were forced to chain dials early, and can't do 2.), a turn before you lose sundial chain
3.) Check and make it waste a purify by aflatoxin healthy creature, or through a ball at it if SoPa's not out to damage him.
Basically the only challenge with Scorpio is purify, always doing a check for purify before playing a SoSa is what is needed to be done.
Morte,
If a lot of early virus
1.)
SoPa + Ball without Aflatoxin, let it burn the viruses to try to kill the ball over 1 to 3 turns, and then aflatoxin the ball.
Otherwise use:
SoSa and Aflatoxin to cut down on the number of viruses.
Remember it takes 3 plague to start to really effect you.
2.)
Play Aflatoxin on it's side of the field to fill it's field to cut out viruses and RoL,
Also Aflatoxin RoLs when you can too... to cut down on need for OTK.
Morte is always a high TTW FG for this deck, instead of 12, expect to be out there for 17 turns.
Morte has 3 challenges, Miracle, Plague, and Bone Wall, however this deck has counters to all three, it's a matter of using the counters correctly and suddenly Morte seems easy. At first I thought Morte was impossible when playing this deck myself, some of my early posts say as much, but then with a few more games, I figured it out, now he seems simple to me.
In general without these tricks, you will win only 50% of the time playing normally against these two FGs.
Using those tricks, you can get it up to 70% to 80% of the time you meet them.
