How does the mechanic "double strike" in Magic: The Gathering affect the strategy of blocking during gameplay?

The mechanic "double strike" in Magic: The Gathering allows a creature to deal damage twice in combat - first during the first strike combat damage step, and then during the regular combat damage step. This affects the strategy of blocking because players need to consider the potential for double damage when deciding how to block attacking creatures with double strike. It may require players to adjust their blocking strategy to minimize the impact of double strike creatures on their own creatures or life total.
