Sire of Seven Deaths is a colorless combat threat that covers several jobs at once. First strike and trample make blocking difficult, vigilance keeps it available after attacking, and reach lets it defend against flyers. Lifelink turns its damage into a substantial life swing, while menace asks opponents for more than one blocker.
It does not require colored mana, and Eldrazi support such as Eldrazi Temple can help cast it. Unlike Eldrazi built around cast triggers, its value is largely in the creature itself, so putting it onto the battlefield through reanimation can still deliver the main package.
Ward makes targeted interaction cost seven life, a significant payment when life totals are already under pressure. Opponents can still choose to pay, and untargeted sweepers or sacrifice effects avoid that ward cost. The card does not draw cards or remove permanents on arrival, so haste or protection can help ensure the seven-mana investment contributes before it is answered. A deck that already produces abundant mana may prefer this kind of self-contained attacker when it needs lifelink and defense in the same slot. Its appeal is dependable combat utility, with enough overlapping abilities to make both attacking and blocking uncomfortable for the other side.
