Problem with some challenge modes (ABC, 123, maybe others)

[Xanathar]

Hi!
First of all.. thanks for the great software! Manalink 2.0 works wonders and is very funny to play for me (an old magic player who has completely abandoned the game the last 5 years and now have only the computer to play.. and no money to spend on crappy virtual cards online ).

But I have a question.. I have a problem in getting my deck accepted in some of the challenges. For example in challenge ABC I proposed this deck and I constantly get insta-killed after mulligan.
The deck I'm using seems to be T1-compliant and all starting with the mighty G (which leads to bad lands to be used and crappy mana development, but that's another problem )

Lands:
4 Great Furnace
1 Gaeas Cradle
4 Gargoyle Castle
4 Geothermal Crevice
4 Gruul Turf
1 Godless Shrine

Red:
4 Goblin Bushwacker
4 Goblin Chieftain
4 Goblin Lackey
4 Goblin Piledriver
2 Goblin Sharpshooter
2 Goblin Warchief
4 Gempalm incinerator
2 Goblin Polka Band
3 Goblin Ringleader
1 Grim Lavamancer
4 Goblin Grenade
2 Gamble

Artifacts:
2 Gauntlet of Might
2 Grafted Skullcap
2 Ghostfire

As I see it, it should be compliant with the rule.
Also I have another deck almost-mono-blue which is always insta-killed in 123.. and I have triple checked I have only the right mana costs and have 4 Islands plus 4 for each blue dual land.

Am I doing something wrong - is something special need to be done to have the deck accepted ?

Thanks!
Xan

Few things to try with something like this...

1.) Reload Magic Constructed a few times if you were in a previous challenge then tried to do that one it can mess it up if you don't restart the program.

2.) Try loading up like Magic Limited then Magic Constructed again sometimes that can reset the card files, sometimes that can cause problems like your putting in goblin pile driver and it thinks its a different card due to a file that didn't get fully changed.

99% of the time those things will fix it the rest of the time you have a real problem on your hands .

Wow! You hit it! Exiting, running limited, starting a new sealed with zendikar, aborting, running constructed and it worked!

Thanks!
