If you want to build a deck around Dragonic Kaiser Vermillion, it is key to have at least 2 Demonic Dragon Berserker Garuda. This will let you unflip the damage and use Vermillion's Limit Break more easily than hoping for a Heal Trigger.
Before using Vermillion's Limit Break and its Counterblast, if you would want to, call Malevolent Djinn and add it to the Soul three times to increase Vermillion's power by 9K along with a boost from Photon Bomber Wyvern. However you should only do this if you know victory is near or you really need that extra power. It is not wise to just move Malevolent Djinn to the soul as it is a valuable 10K shield.
Anti-Strategy: An opponent facing this card could restrict Vermillion's power by playing only one other Rear Guard in the front row, which makes it impractical to Counterblast three valuable damage to defeat one enemy. However, you still end up with an advantage as it means less rear guards that can attack you. Alternately, one can play the least desirable units on the rearguard circles, specifically units that aren't useful as rearguards or in the hand, therefore meaning the loss of those units won't be a big impact. Do note though that retired units are still a loss of units and thus a loss of card advantage.
This card is also ideal when combined with Dragonic Deathscythe. This unit can deal with any rear guard boosters (particularly those that can cause you to need to defend with more than 10000 shield), while Vermillion can use its Limit Break to retire powerful attackers, emptying the field, and consequently the hand.
