March 16, 2021 Rules revision refers to rule changes made to the General Game Rules made on March 16, 2021.
Details[]
The official announcement of rule changes include the following;
- Rebuilding
- Cards under other cards in the battle zone
Both rules relate to how an evolution creature and the cards underneath may stay in the battle zone after Card Based Removal or the "Degenerate" term (removing the top card) may affect them.
This revision was due to the new Star Evolution Creature and the Star Evolution keyword, to have simpler and concise ruling.
Rebuilding Rules Revision[]
Old Rule: When only the top card of a creature leaves the battle zone, if that card was an evolution creature, you would choose one or more of the creatures underneath according to the evolution type, and leave them in the battle zone as separate creatures. Any other cards would be put into the owner's graveyard. If the top card was not an evolution creature, all cards underneath would be put into the owner's graveyard.
New Rule: When only the top card of a creature leaves the battle zone, the cards underneath remain stacked in the battle zone. If the top card wasn't an evolution creature, all cards underneath are put into the owner's graveyard.
- For example, if you had an evolution creature with the Galaxy Vortex Evolution ability, and 3 non-evolution creatures underneath. Under the old rule, when the top card left the battle zone, the 3 creatures underneath would remain as 3 separate creatures. Under the new rule, the 3 cards stay stacked together (as one creature with 2 cards underneath) in the battle zone.
- Under the old rule, the number of creatures that could remain in the battle zone depended on the evolution type of the top card that left. Under the new rule, regardless of what the top card was, the cards underneath remain as one stacked creature.
- If one of the cards underneath was itself an evolution creature, and there was no valid evolution source among the remaining cards, under the old rule it would be put into the graveyard. Under the new rule, no special handling is done and the stack simply remains in the battle zone as one creature.
- This rule change only applies to rebuilding after a card with an evolution trait leaves. If the top card of a creature stack doesn't have an evolution trait but has cards underneath (e.g., a non-evolution creature played via Gate of Moonless Night), the rest of the stack is still put into the graveyard as before.
Cards under other cards in the battle zone[]
Due to this rule change on rebuilding, the concept of order was introduced for cards under another.
Under the old rule, card order had no impact on the game, and since you could choose any card to remain when rebuilding happened, there was no reason to distinguish or preserve order, so rearranging was allowed.
- When putting multiple cards underneath a creature simultaneously, such as with Vortex Evolution, the order in which those cards are stacked is decided. The player who puts the creature into the battle zone may choose this order freely.
- When putting cards under another, they are put at the very bottom of the stack (Comprehensive Rules 403.4a). For example, this applies to cards such Time Changer, Space-Time Engineer and Timeless Garden.
- The order of cards placed under can't be rearranged afterward.
- If the top card in the card stack can't stay in the battle zone, cards are put into the graveyard one by one from the top until a card that can remain as a creature is on top.
- For example, if in the battle zone there is a stack with, from top to bottom: Dark Matter, Zenith of "Magic", spell, spell, Twinpact card, Twinpact card, spell, spell, when degeneration occurs, the closest Twinpact creature from the top remains.
