Vengeant Earth
Green rarely gets to dictate combat this directly, and the trick here is bundling three effects into one instant so the lure actually has teeth. Animating a land you control into a 4/4 haste Elemental is the ramp payoff and the surprise attacker rolled into one: a creature that was a Forest a moment ago suddenly swings for four. The must-be-blocked clause is what turns that animation into removal, and it is where green's usual clumsiness gets patched. Green's answers to problem creatures are historically awkward (fight spells that put your own body at risk, deathtouch bites that need a creature already in play), but forcing a block sidesteps that entirely. Attack a player who has only one legal blocker, or attack when the trade you want is the one they can least afford, and the compulsion does the work: they must throw a creature into your 4/4, and the four damage is almost secondary to bleeding a body off the board. Pointed at a real creature you already control, it reads as a lure with a 4/4 body stapled on, marking one of your threats as the one they are obligated to answer. To swing with an animated land, though, you have to act early: cast it during the beginning-of-combat step or before, since attackers are locked in the instant declare-attackers begins and a land woken up after that misses the wave entirely.
