Here is my collection of Gods Unchained F2P deck guides.
@meltysquid/gods-unchained-f2p-welcome-core
Nature is probably the best God to start with since a lot of their Welcome and Core cards are at common and rare and the strategy is straight-forward. There are some strong Divine Order cards at common like Brazen Moose and Giant Pangolin.
@meltysquid/gods-unchained-f2p-welcomecore-slayer-war-deck
Slayer War is another easy God to start out with since it can be competitive on a budget. It is currently one of the best decks in the meta. This deck is the fastest deck in the game, great for finishing your weekend ranked games and Blessing of the Gods.
@meltysquid/gods-unchained-f2p-welcomecore-zoo-light-deck
Zoo Light is decent to start with as a beginner. Light has the best buffs and is great at building a board although it struggles to come back from behind. Budget Light is decent but not top tier, most of Light's strongest cards are expensive like Highborn Knight and Cudgel of Atonement.
@meltysquid/gods-unchained-f2p-welcomecore
Magic has the best spells but as a tradeoff it has understatted creatures. It uses removal to set the opponent back while setting up their own strategy. Play creatures out, keep the opponent's board empty with your removal and gain tempo, wear down your opponent, then finish them off with your big damage spells.
@meltysquid/gods-unchained-f2p-welcomecore-hidden-rush-deception
Hidden Rush Deception is a fast paced deck using low cost creatures and removal to gain tempo, wear down your opponent, and finish off your opponent with hidden creatures. The budget version is good since there are new common and rare Divine Order cards that do well for the deck.
@meltysquid/gods-unchained-f2p-welcomecore-aggro-death
Aggro Death is a hyper-aggressive deck that uses its cheap creatures to hit face hard and fast and finish off the opponent with reach from self-damage cards like Bombfly, Brimstone, and Soul Burn.
