Give your opponent a Spirit monster, and it will still return to your hand at the End Phase, which essentially gives you costless monster removal.
A monster of your own that is unaffected by Spell Cards can be targeted to simply destroy an opponent's monster without any cost.
Give your opponent control of "Miracle Flipper" with this card, and then attack the "Miracle Flipper". Once it's destroyed, it will come back onto your side of the field, which in essence lets yourself destroy your opponent's monster without a cost.
If your opponent only has one monster on the field, use this card with your "Puppet Master".
Destroy an opponent's strong monster and give them a Token (preferably from "Scapegoat") in return.
Damage can be inflicted to your opponent if this card is used with "Mist Archfiend". First, Normal Summon it without Tribute, destroy a weaker monster if they have 2 or more monsters, and then use "Mystic Box" in Main Phase 2. This card can also be used to inflict damage with "Zombie Mammoth" if the opponent doesn't use Zombie-Types.
Give your opponent a searcher monster such as "Sangan", and then attack it with your own monster to get its effect.
This card can work well in a "Gusto" Deck. Most effects of "Gusto" monsters are activated when destroyed by battle such as "Gusto Thunbolt". Give your opponent one of these monsters while destroying theirs in the process. Then proceed to attack the given monster and Special Summon another "Gusto" monster in the process. This can work especially well with "Windaar, Sage of Gusto".
This card can also be used on "Number 30: Acid Golem of Destruction". After using up its Xyz Materials, use this card to give it to your opponent, making them take 2000 damage during each of their Standby Phases and preventing them from Special Summoning.
Use this card with "Vengeful Servant" to inflict damage to your opponent if the control of a face-up monster on your side of the field is changed.
