I can only agree with Baphomet (a demon like me
) since sower of temptation is a card from the LORWYN set, would be easier if you could post these can of specific bug in the corresponding thread...
Also regarding sower of temptation, it is creature with an automatic "control magic" so I though i will use the alias and the targeting function, but as you can see it does not work. So this one will be taken away from the next lorwyn release.
Regarding the "shop" crash it happen only if you go again and again in the shop (something like more than 6 times in a row) also to avoid this bug, just play some game or go in deck editor every 5 or 6 times you enter the shop in a row..
Regarding the merfolk thing, could it be because the AI blocked with merfolk and merfolk lord and both were damaged and were on the way to the graveyard ? Because that is what happen from time to time to me with "zombie master" and "zombie" also I am gonna check this one with the test suite, but currently I'm guessing it has something to do with the "lord" abilities, if it is the case a simple test from the test suite will help to figure it out.
Regarding cards limitation, well it someting you can do "manually" i mean it is not really a bug...
Finally, spark elemental is from the "tenth edition" also it was probably something wololo did not see...
