Q2: Does {{Overflow}} apply when I use this card's All Turns effect to place this card in the digivolution cards of the played Guilmon?
No, it doesn't. {{Overflow}} applies when a card from the battle area or from under a card is placed into another area. In this case, it doesn't apply because a card from the battle area is placed under another card.
Q3: What does an "add X000 to the maximum your DP-based deletion effects can delete" effect do?
Such effects increase the maximum value shown for DP-based deletion effects. For example, while "Your Turn Add 1000 to the maximum your DP-based deletion effects can delete" is activated, "When Digivolving Delete 1 of your opponent's Digimon with 3000 DP or less" will allow you to delete an opponent's Digimon with 4000 DP or less.
Q4: If "add X000 to the maximum your DP-based deletion effects can delete" is activating, can the maximum be increased for an effect such as "delete 1 of your opponent's Digimon with DP less than or equal to this Digimon's DP" that references a Digimon's DP for deletion?
No, it can't be increased. You can't increase the maximum of a DP-based deletion effect that doesn't show a numerical value.
Q5: What does "DP deletion effect limit +X000" mean?
This effect adds the upper limit of the value texted in the DP deletion effect. For example, while "On Opponent's Turn Upper limit of DP deletion effect you activate +1000." is active, "When Digivolving Delete an opponent Digimon with a DP of 3000 or less." will cause the opponent Digimon with a DP of 4000 or less to be deleted.
Q6: While the "DP Deletion Effect Limit + X000" effect is active, can I add an upper limit to the effect of "Deletes opponent's Digimon whose DP is less than or equal to this Digimon's DP." Can I add an upper limit to the effect of deletion by referring to the Digimon's DP, such as "This Digimon's DP is less than or equal to the opponent's Digimon's DP.
No, it cannot be added. You cannot add the upper limit of a DP deletion effect for which no numerical value is texted.
