Winds of Abandon offers a small answer early and a one-sided creature reset later. For two mana, it exiles one creature you do not control. Paying the overload cost changes the spell to exile each creature you do not control, preserving your own board for a potentially decisive attack.
Exile can deal with indestructible creatures and prevent ordinary graveyard recursion from bringing the removed creature back. The overloaded version does not target, which can also matter against hexproof or protection. Because the spell is a sorcery, you normally use it during your own main phase rather than waiting to answer an attack on someone else's turn.
The compensation is basic lands. For each creature exiled this way, its controller can search a basic land onto the battlefield tapped. Clearing a wide board can therefore give opponents a considerable amount of future mana if their libraries contain enough basics. That makes the timing important: removing blockers and winning or establishing a dominant position is better than handing out several lands without a useful follow-up.
Creature-heavy white decks can use the overload mode to turn a stalled battlefield into an open attack. Keep the cheaper mode available when one creature is the actual problem; you do not have to save the card until six mana. Evaluate both the creatures removed and the mana granted. The spell is most effective when the immediate advantage of keeping your army outweighs the resources opponents will gain on their next turns.
