If a Dragon Synchro Monster is on the field: Special Summon up to 2 monsters, that are "Resonator" monsters and/or Level 1 Dragon monsters, from your Deck. When a monster effect is activated, while you control a Level 10 or higher DARK Dragon Synchro Monster: You can banish this card from your GY; negate that effect, and if you do, 1 Synchro Monster you control gains 2000 ATK until the end of the next turn. You can only use each effect of "Time to Stand Up" once per turn.
