Illusions are your primary threat , as they're bigger than non-vanishing characters , and can be easily brought back into play with Jafar
Between access to mana, cards, and direct damage, it adapts easily to what you need most, while untap effects and protection help you squeeze maximum value out of every activation

Because you have Blightsteel you could cut Darksteel since it's much worse, not really needed, for Spellskite to protect
That gives you some room away from big scary creatures for at least a turn, letting you push back any devastating attacks and/or clearing some runway to get damage through
