For this kind of battles I like to use a card with the Taunt ability in the first position, and followed by a card with the REFLECTION SHIELD ability, that helps a lot to concentrate the explosion in a single point and not to do extra damage to other cards.
I like this strategy that you use, more for the fact of using a card with the Martyr ability, that's a good strategy my friend.

Thanks my brother, undoubtedly the strategy you propose seems to be a great move, in fact by doing it without the "divine shield" ability you can position a tank that reduces the impacts, thanks for commenting, greetings!
