Squee's Embrace

Most Auras carry a hidden tax: when the creature underneath them dies, the enchantment dies too, and you have spent two cards to the opponent's one. This one rebates the half of that exchange that actually hurts. The +2/+2 makes the host bigger now, but the death trigger returns the creature card to your hand, so a removal spell, a chump block, or a forced sacrifice all trade down for your opponent instead of for you. The Aura itself still goes to the graveyard, so the loop is finite; what you recover is the body, which is the expensive end of a two-for-one. That recursion is what separates this from a plain bear-pump like Unholy Strength or Holy Strength: the card turns a flimsy creature into a resilient threat, and it pays a premium when stapled to something with an enters-the-battlefield effect, since each return refunds the trigger for a second cast. The red-white pairing belongs to a design era that took the formerly unfriendly two-color combinations and built around them, leaning here on small aggressive creatures that wanted to keep swinging through bad blocks. As an enabler it is honest about its limits: it does nothing against exile or bounce, and it still asks you to commit two permanents to one creature. What it offers in return is staying power, the rare creature buff you are happy to see your own attacker die under.
