Among recent MTG black cards, few close games this cleanly without committing to combat
The latter is horrible but it is some devotion at least
Apocalypse Runner, the other signpost gold uncommon, can help smaller creatures push past blockers, effectively increasing your speed the turn it comes down
Render Silent Three mana is on the expensive end for counterspells, but Render Silents ability to put a stop to any more of your opponents nonsense this turn makes it one of the best for controlling the game
If a card doesn't specifically use the word win, there's no winning outcome, so a cards like Two-Headed Giant won't ever trigger a payoff like Zndrsplt, Eye of Wisdom
If you control Sphere of Safety, your opponents can choose not to pay to attack with a creature that attacks "if able." If there's no other player or permanent to attack, that creature simply doesn't attack
