There are plenty of Knights that care about combat, as well as white cards that make it easier to give stat boosts to all of your creatures
The regenerate and hexproof abilities return to hand to be used again if they should drop off or be used, and several of the removal abilities are tied to creatures I can then kill off, bring back as lands, and then use again
Seriously, my advice is to avoid playing this color combination even if it appears open, and even if you get a good rare or two
Bonus points if you can benefit from casting spells from other zones
Do you want to win by going real hard over the top with damage
You can pick up a copy of Lorcana: Gateway directly from Ravensburger, from Amazon, your local big-box store, or from your Friendly Local Game Store (they can tell you all about collectible card games!)
