One of the most difficult restrictions to make is the one that restricts us to 12 energy since at least for me it is difficult to choose the best one since with that level of energy, we can only use 1, 2 or a maximum of 3 cards but yes that It has very little mana, they can have little life and it will make them vulnerable.

BATTLE CONDITIONS

On this occasion, the combat rule only allows using cards with a ranged attack, so I have to think about what cards to use and, above all, that I should put one that attacks from the first line.

Additionally, we can only use 12 energy, which greatly restricts us to using more than one low-mana card or just one card. We can also use all colors except black and dragon.

My Team

GENERAL SLOAN

This summoner is very good at the battle rule that only allows you to use cards with a ranged attack, since this would allow you to increase the ranged attack by +1, which will allow us to beat the opponent faster and its level 3 will allow me to summon cards high level.

GARGOYA DEVIL

This card will be the only one I will use that allows me to invoke the low level of mana available.

It has 3 speed that will increase the possibility of dodging attacks, which is enhanced by its flight ability, which further increases this possibility of dodging attacks.

DEVELOPMENT OF THE BATTLE

RONDA 1,2,3 and 4

On turn 1 and turn 2 my enemy attacks me twice and only on the third turn does his XENITH ARCHER manage to land 1 attack on him, taking away his shield.

While my GARGOYA DEVIL is attacking and manages to eliminate his MOLTEN ASH GOLEM before it attacks on the third turn, which means that his Eliminate my enemy.

LAST CONCLUSIONS

The key to victory is in this case the FLIGHT capacity of my GARGOYA DEVIL, which added to his 3 speed, is what gave him the chance that of the 4 attacks that my enemy was able to make, that if they had been successful, he would have achieved eliminate my card and I would have won.

Additionally, my summoner by increasing the attack level of my card allowed me to eliminate my enemy quickly before he made more attacks that could hit his attack and eliminate my GARGOYA DEVIL.
