If your LP are lower than your opponent's: Add to your hand, or Special Summon, 1 "Elemental HERO" monster, "Kuriboh" monster, or "Neo-Spacian" monster from your Deck or GY, with ATK less than or equal to the difference in LPs, also for the rest of this turn, you cannot activate cards, or the effects of cards, with the same name as that card. You can only activate 1 "Generation Next" per turn.
Can only Special Summon monsters with ATK equal or less than the difference in LP.
Since Kuriboh monsters have very low ATK, it is highly likely you can search them when your LP is lower than your opponent. Can be used similarly with The Flute of Summoning Kuriboh to search Kuriboh to your hand or Winged Kuriboh to your field.
The Neo-Spacian monsters all have pretty low ATK. Search the one you want to use as fusion material with Elemental HERO Neos. As a comeback option you can use this card to search a Neo-Spacian and discard it with Convert Contact to draw 2 cards.
