Of course, purchasing Jumpstart sets wont quite work for making Booster, Standard or Commander decks and would likely end in sadness for anyone attempting such a feat
Drawing four on cast regardless of anything else is great, even if its countered, and Annihilator 4 is going to be a problem to deal with
Cards that generate additional mana, like Mana Reflection, Mirari's Wake, and Nyxbloom Ancient, can help accelerate your mana production and enable you to cast this powerful monster and other devastating ones like Avenger of Zendikar
Four mana for a one-sided Howling Mine is already not the worst place to start, although that on its own would hardly be impressive
Although higher numbers of Endurances are found in sideboards than in the maindeck, I wouldnt be surprised if decks include more Endurances maindeck already considering how much flexibility this card gives
