If your Harpie monster gets destroyed, you can special summon them again using Time Machine. This will bring back your monster, and activate the field spell's effect again.
Special Summon when destroyed
Using Time Machine on monsters that can special summon when they get destroyed will allow you to re-use them again. When your opponent destroys your monster, you will end up with 2 monsters on the field instead.
Activate when special summoned
Cards like Gemini Scorpion, or Delta The Magnet Warrior have effects that will activate right away when they are normal summoned, and/or special summoned, allowing them to use their ability twice with only 1 monster.
Using Time Machine on Lv1 will let you special summon Lv3 on your next turn if it doesn't get destroyed, which can total up to +4 extra draws if all the mimics get destroyed. It is also fine if you use Time Machine on Lv3 instead, since you get the draw when it gets destroyed by battle.
Basically has the same effect as Time Machine but the monster will get destroyed at your End Phase and it can only be summoned in defense position. It can prevent damage to your Life Points from an attack. Use Regretful Rebirth first before using Time Machine if you need the monster to stay on the field.
This combination is very effective when you have a monster that has an effect that activates when it get destroyed by battle and sent to the Graveyard. E.g. Warm Worm and Blue Dragon Summoner.
Has similar effect as Time Machine. It can only summon normal monsters, can be used outside of Damage Step and the monster can only be summoned in defense position. This card can prevent damage to your Life Points from an attack. You can revive any normal monster regardless of level, type or attribute. It can also be used if you needed a monster for a tribute.
Special Summons from your Graveyard / Special Summons from your opponent's Graveyard
Can someone explain this to me? Farming Pegasus using the 3SD deck listed on this website. I stall with buster blader, he summons copycat and a turn later toon mermaid. Copycat destroys buster blader but time machine that is face down doesn't activate. Why?
Can't wait for this card to come out! With the warm worm card x3! (The card where opponent discards 3 random cards) maybe even pair it with a few cocoon of evolutions.
Imagine this x3 paired with regretful rebirth x3 paired with shallow grave x3!
