Personally, I would mold this deck by including more cards with the storm mechanic, fast mana, and things like Thousand-Year Storm to get even more value out of Kalamax
Perhaps because this blue creature has been erratad to a surveil 1 which isnt on the card
In addition, whenever another creature enters the battlefield, its controller can draw a card if that creatures power is creature than every other creatures
Probably running a legend without exalted is where
Scan cards on your desk, a dark table, or directly from your hand
I think this happened enough that it was clear that more answers to planeswalkers were needed, and now most removal spells can directly destroy planeswalkers
