I recently bought a card called Silver Shield Sentry in the game Splinterlands. I thought it would be a simple melee card, but when I used it, I realized that it is actually much more powerful. According my own experience, this card can completely change outcome the match.

The first thing that caught my eye attack power. It seems to do 3 damage at first glance, but the real thing is that this card has a Double Strike ability. That means it hits twice per round, not once. So if you calculate it, it can do a total 6 damage per round. I found this a very big advantage, because it weakens the opponent's cards very quickly.

When I used this card in the first few matches I realized that placing it right place is very important. If I put it right in front dies quickly. But when I put it in the second position, its real power comes out. If you have a strong tank in front, Sentry can safely attack from behind and get the full benefit of its Double Strike.

Another thing I noticed is that this card works very well at breaking Armor. Many times the opponent's card has Armor first, which takes time to break. But since Sentry hits twice, it breaks the Armor on the first hit, and deals direct Health damage on the second hit. This weakens the opponent quickly.

I also noticed that this card becomes much more effective in certain rulesets. For example, when there is a rule where all melee cards can attack from all sides, then this card becomes absolutely terrible. Because then it can not only deal double damage from the front, but also from any position. Also, in a ruleset where all cards have equal health, then it survives longer, so it can deal more damage.

However, like everything else, this card also has some weaknesses—I realized this while using it. For example, if the opponent's card has Thorns, then there is a problem. Because when Sentry hits twice, he also takes damage twice. As a result, many times his own card dies quickly. Also, I feel that it is a little weak against magic attacks, because magic attacks directly affect health.
I will say from my own experience, this card is not much alone, but when used with the right team, it works wonderfully. For example, if there is a good tank in front, along with a healer, then the tank lasts a long time and Sentry can deal continuous damage from behind. Also, if there is a card that increases melee damage, then Sentry becomes even stronger.

I have also seen the issue of increasing the level. Although its attack is 3 at the beginning, later when you increase the level, the attack and other stats increase. Then it becomes even more dangerous. So I think, if you want to use this card, then gradually increasing the level will be a good decision.
Since I bought this card, I was also thinking about the price. I think the price I paid for it wasn't bad. Because it's a card that can be used in many matches and can be easily won if used properly. It's a great option, especially for those who play with Life Splinter.
Overall, I would say that Silver Shield Sentry was a great purchase for me. At first, I bought it just because of the damage, but now I understand—its real power is Double Strike and proper use. Now I try to set it up well almost every match because having it increases my chances winning a lot.
my own opinion is—this card is not only good, but if used properly, it can be a game-changer in match. So I will use it in the future and try gradually make it stronger.
