First eith the Card combination not working (all the time) the Land "Tolarian Academy" witch reduces the cost of artifacts by one does not always reduce the card "Sylvan Shrine" for 4 to 3 as it should (This only happens when I make a new deck and not even all the time but does not fix itself until the deck is remade).

Random Cards in starting hand is the second issue, I notice in about 1/5 of my matches there is a random card in my hand, could be a blue red Mythic creature to a Green common spell and this applies to anyone I am dueling with any Planes walker main. I do not understand why this happens and is really quite confusing when it does as I will have a Blue sphinx in my red white deck out of no where.
